I want to ask everyone a basic question , Why anybody does not use original Kodak,Ilford,Fuji or others technology to sensitize their emulsions ? I saw PE had posted a list also .
I think someone could buy a good amount of sensitizer which had been produced for EFKE, Foma.
I dont think EFKE invest Kodak money to the chemicals in Croatia , they might have a local source !
There are thousands of patents waits to be analyzed in Europe and US also.
That is handwaving but I start to research from poorer manufacturers , Russian and East Europe and China.
Chris , invest your time in www.alibaba.com. China is very cheap to find chemicals.
