Try google patents or uspto.gov server but its a pain to find the suitable plug in to watch images with goverment site. So google patents is best but its search engine is not correct I guess. It can give unrelated documents but not whatever you want. You must indicate the years at below and get tired , furious after few hours.
Lets ask the right question , what gives velvia , velvia look , kodachrome , kodachrome look.
I had been asked before to create the inkjet inks from kodachrome formulas.
Lets get practical , If we treat these colorless inks with developer and get the real colors and if we do every photoshop trick , do we get kodachrome look print ?
Or do we need extra step and make rgb kodachrome gel coated filters and tricolor process and scan , than photoshop and print with kodachrome cmy processed inks.
If this will give me homemade kodachrome , lets start from somewhere.
I am talking about inkjet.
The dyes give the Kodachrome look. With those dyes, you can recreate even digital Kodachrome. Blah!
I am having problems with the Adobe plug in. My search works, but I cannot see the file. I get an Adobe error message.
With a great possibility , your computer is infected. Some hackers or robots use flash plug in as the door inside the computer. So try to load flash , if it does not work , it does not work anytime , so you need to reinstall the windows. Youtube videos , nude art photography sites are responsible.
Yes , I want my kodachrome back with chemistry and some computer , mechanics replaces the hard work.
So you are the expert and became dominant force and responsible person from experimenters.
Please tell us how can we color these colorless inks , how we will prepare the colorless inks and color them.
Patents are for skilled persons and we are the least on this subject.
Some can be toxic , some can have no needed to contact with air , temperatures , processes and the mixing procedure , ...... etc etc.
You dissolve the coupler in a solvent and add alkali. Then add a solution of CD3 in water. Add some peroxide and watch the fun. Color will form instantly and get deeper and deeper. Use a Separatory Funnel with a solvent plus this dye mix to extract the dye into a suitable solvent such as hexane or benzene, and then evaporate the solvent until you have solid dye. You may have to cool the reaction mixture during dye formation in order to prevent oxidation of the dye or overheating!
Use as prescribed by your handy digital engineer. You are now outside my field.

That is, of course, the correct patent. And now, my acrobat reader is working. I had to shut down Mozilla and restart it, then it crashed and sent a report, and then I started Acrobat as a stand-alone program and within IE. Then, back to Mozilla and all was fine. My system checks free of virus contamination.
Be careful about flash if you use windows. If your computer starts to slow down , be sure something going on.
I tried to understand the patent and if I am not wrong , it gives developer formulas , not couplers as you indicate to me to prepare my solid dye.
There are many coupler patents listed and of course I dont have any clue which one used.
May be I am understanding everything wrong and these developers are the couplers but really I have no idea , I am sorry for the newcomer if I drive him her to wrong direction.
PEs posts are the reference , no way mine
Can you give me these couplers formulas and preparation details.
Happy New Year ! Its 3 AM here.

The 3 couplers and 2 developing agents are there in the formulas. For example, OTOMH, the cyan is a Napthol derivative and the magenta is a Pyrazolone. The yellow is probably an Acetoacetate. I checked the formulas beforehand, and they are there and are complete.
Thank you PE , You are great.
incorporated couplers is as follows: --------------------------------------------------------------------------- Color Developing Composition I
benzyl alcohol 0-12 ml. Alkali metal hexametaphosphate 0-3 g. Alkali metal sulfite 2-20 g. Tri alkali metal phosphate .sup.. 12H.sub.2 O 10-60 g. Alkali metal bromide 0-5 g. Alkali metal iodide (0.1 % soln.) 0-15 ml. Color developing agent of Formula I 0.5-15 g. Ethylenediamine sulfate 0-20 g. Citrazinic acid 0-5 g. Dithiooctanediol 0-5 g. Water to 1 l. __________________________________________________ ________________________
and sufficient alkali, e.g., alkali metal hydroxide, alkali metal carbonate, etc., to adjust the pH in the range of from about 10.0 to about 14.0. The alkali metals used to advantage to make the compounds of the color developing composition are sodium, potassium, lithium, etc. Typical color developing compositions used to advantage in processes of our invention for photographic elements that do not contain couplers are as follows: --------------------------------------------------------------------------- Cyan and Yellow Color Developing Compositions
Alkali metal hexametaphosphate 0-3 g. Alkali metal sulfite 3.0-20 g. Alklai metal bromide 0.2-5 g. Tri alkali metal phosphate .sup.. 12H.sub.2 O 20.0-60 g. Alkali metal iodide (0.1% solution) 2.0-50 ml. Color developing agent of Formula I 0.5-10 g. Antifoggant (1% solution) 1.0-40 ml. Alkali metal sulfate 0-70 g. Diffusible coupler 0.5-8 g. Hexylene glycol 0-20 ml. Diethyl hydroxylamine (85%) 0.3-10 ml. Competing coupler (e.g., citrazinic acid) 0-8 g. Auxiliary developer (e.g., 1-phenyl-3-pyrazolidone) 0.1-2 g. Alkali to produce a pH in range of 10-14 Water to 1 l. __________________________________________________ ________________________
In this composition, a phenol or naphthol cyan-die-forming coupler is used in cyan developing compositions and an open chain acyl acetamide type yellow-dye-forming coupler is used in yellow developing compositions. Antifoggants, such as, 5-nitrobenzimidazole, 5-nitrobenzimidazole-6-nitrate, etc., are used to advantage as the antifoggant. Any of the alkalis used in photograPhic developer solutions are used to advantage in the color developing composition including alkali metal hydroxides, alkali metal carbonates, borax, etc. The alkali metals used to advantage to make the compounds of the cyan and yellow color developing compositions and the following magenta color developing composition are sodium, potassium and lithium.
MAGENTA COLOR DEVELOPING COMPOSITIONS
These are the same as the cyan and yellow developing compositions, except that they do not contain an auxiliary developing agent or any antifogging agent, but they do contain in addition to the cOmponents listed above:
Alkali metal thiocyanate 0.3- 5 g./l. Ethylenediamine 1.00- 8 ml./l. A chemical fogging agent for silver halide 0-2 g./l. __________________________________________________ ________________________
Chemical fogging agents used to advantage include the nucleating agents of Hanson et al., U.S. Pat. No. 3,246,987, e.g., the amine boranes (e.g., trimethylamine borane, diethylamine borane, triethylamine borane, tert-butylamine borane, pyridine borane, 2,6-lutidine borane, etc.), the polyamine boranes (.e.g, ethylenediamine diborane, hydrazine diborane, etc.), a phosphine borane (e.g., dimethylphosphine borane), an arsine borane (e.g., dimethylarsine borane), a stilbene borane (e.g., dimethylstilbene borane ), a borazine (e.g., borazine, N,N',N'-trimethyl borazine, N,N',N"-trimethoxyborazine, etc.). When no chemical fogging agent is used in the magenta color developing composition, a chemical fogging bath is advantageously used just prior to the magenta color developing composition or, alternatively, the unexposed green-sensitive silver halide emulsion layer is made developable by exposure to light. A typical chemical fogging bath has the composition:
Alkali metal hexametaphosphate 0.6 g. Alkali metal hydroxide 2.16 g. Chemical fogging agent for silver halide 0.10 g. Water to make 1 l.
Any of the chemical fogging agents listed above are uSed advantageously in this composition.
