Abstract

PURPOSE: To obtain a photographic material having stable equality and low post- hardening tendency with time, without lowering the photographic characteristics such as fog, sensitivity, etc., of the emulsion, by reacting a 2-imidazolidone derivative with gelatin.
CONSTITUTION: Gelatin is made to react with a compound of formula [R is H, alkyl, substituted alkyl, substituted phenyl, -CO(R1) (R1 is alkyl, substituted alkyl, phenyl, substituted phenyl, alkenyl, substituted alkenyl, alkoxy, amino, substituted amino), -SO(O) (R2) (R2 is alkyl, substituted alkyl, phenyl, substituted phenyl)]. The gelatin may be partly substituted by colloidal albumin, casein, carboxymethylcellulose, polyvinyl alcohol, etc.
