Helen;

That is good for an approximation only. As it says, this is for a chlorobromide emulsion and all film emulsions that I know of are bromoiodide, therefore the spectrum and reactions will be different.

These particular dyes may not even work on a bromoiodide or they may form "J" aggregates. We had tables of dyes with emulsions, pH, pAg and etc at EK that could be used to pick and choose.
