UV-Stabilized photographic elements |
摘要 |
Inclusion of a stabilizer selected from phenyl and naphthyl esters of benzene and naphthalene carboxylic acids and mixtures thereof in an article, e.g. a photographic element, comprising an organic dye or precursor thereof increases stability of the dye against ultraviolet radiation. Particularly good results are achieved when the stabilizer is dispersed in a polymer of relatively high solubility parameter and low crystallinity.
