Abstract (en)

[origin: EP0661588A2] Yellowing, dye fade and thermal pinking of a processed color photographic element is improved by incorporating into the photographic element a non-color forming, oil-soluble, monomeric or oligomeric organic compound having a glass transition temperature between 0 DEG and 150 DEG C. The tendency of photographically useful compounds (PUCs) to crystallize when dispersed in an aqueous medium is also inhibited by codispersing with the PUC the non-color forming, oil-soluble, monomeric or oligomeric organic compound. Preferred organic compounds are oil-soluble sucrose esters, such as sucrose octaacetate, and rosin and derivatives thereof. In a particularly preferred embodiment, the above-noted properties are improved by incorporating into the photographic element an oil-soluble rosin derivative, such as abietic acid.
