PURPOSE:To prevent electrostatic charging by incorporating a reactive anionic surfactant in a gelatin-contg. layer. CONSTITUTION:A gelatin contains a surfactant represented by general formula I , II, or III in which R1, R2 is H, alkyl, aryl, alcohol, halogen, acyl, acid, sulfonamide, carbamoyl, or sulfamoyl; R3, R4 are H, alkyl, aryl, or a heterocyclic aromatic ring, and R3, R4 may form a ring with each other; m1, m2 are each an average polymn. degree of 2-40; m3 is 0 or 1; n1, n2 are each 0 or 1; n1, n2 are each a copolymn. molar fraction of 1-100 and 0-99, respectively, and n1+n2= 100. The obtained photosensitive material is not adversely affected in the photographic characteristics, and is not changed with time in charge prevention characteristics, and does not stain a processing soln. and a roller.
