发明名称 FOG RESTRAINER FOR SILVER HALIDE PHOTOGRAPH
摘要 PURPOSE:To maintain stable photographic characteristics even after long-term preservation at an under a high temp. and high humidity by forming the fog restrainer of 1,4,2-dithiazolium salt compds. having a specific heteroarom. cation ring structure. CONSTITUTION:This fog restrainer is used by incorporating at least one selected from the 1,4,2-dithiazolium salt compds. having the heteroarom. cation ring structure into at least either of a silver halide emulsion layer and the hydrophilic colloid layer adjacent thereto. The purpose as the fog restrainer for photographs is attained if the 1,4,2-dithiazolium salts have the cation ring structure in this case. Generation of fogging is thereby suppressed during the long-term preservation or even if the photographic sensitive material is stored at a high temp. or at and under the high temp. and high humidity. The excellent photographic sensitive material which is free from degradation of the sensitivity and softening of the gradation is thus obtd.
