Paper Abstract

I'd like to discuss with you a method that we use in the image stability laboratory for prediction of the effect of residual thiosulfate on the long-term storage of films. The first half of this talk appeared in the April, 1982, issue of the Journal of Applied Photo-graphic Engineering. I'll just be showing selected examples of the data here. Anyone who would like to see all the numbers can find them all tabulated in the publication. At least for X-ray films, high thiosulfate causes D-min discoloration. The second part of my talk will deal with what this discoloration is, both chemically and in terms of its tendencies to appear even after current chemical analyses may indicate that it shouldn't happen. I'll be using stain buildup and D-min discoloration interchangeably. For our purposes, they will describe the same phenomenon.
