摘要:
Static property in a photographic material is effectively prevented by incorporating a specific copolymer formed from, as the copolymerizable components, a betaine-containing polymerizable monomer and a fluorine-containing polymerizable monomer, in the protective layer, backing layer, or an overcoat of the photographic material without exhibiting adverse influences on the photographic properties of the photographic material.

摘要:
A method for processing a silver halide color photographic material which comprises, after color development of an exposed silver halide color photographic material containing a hydrolyzable type DIR coupler, rapidly processing the developed silver halide color photographic material with a liquid having a bleaching ability and subsequently with a liquid having a bleach-fixing ability, to thereby form a color image.In accordance with the method for processing a silver halide color photographic material, desilveration is completed in a short period of time and color photographic images having excellent color reproducibility and fastness are obtained.
摘要:
A method of color photographic processing is disclosed. The method comprises color developing an exposed silver halide color photographic light-sensitive material and thereafter carrying out a bleach treatment and a fix treatment or a bleach-fix treatment, wherein the bleaching agent used for the bleach treatment or the bleach-fix treatment is a ferric ion complex salt or a persulfate and the bleaching bath or the bleach-fixing bath or a pre-bath therefor contains at least one compound represented by the following formula (I): ##STR1## wherein all the symbols are defined in the specification. A prevention of pollution problems and an acceleration of bleaching action without deterioration of photographic properties can be attained by this method.
