PURPOSE: To improve sensitivity, developability and preservable property by incorporating silver halide particles contg. a prescribed content ratio of silver iodide and two kinds of specific compds. into the extreme surface of the photosensitive material.
CONSTITUTION: The silver halide particles having ≤5mol% silver iodide content are incorporated into the extreme surface of the photosensitive material and at least one kind of the respective compds. expressed by the formulas I, II are incorporated therein. In the formula, R1 denote a hydrogen atom, alkyl group, phenyl group, aralkyl group; R2-R5 denote an alkyl group; A1-A6 denote a hydrogen atom, alkyl group, alkoxy group, halogen atom, phenyl group, the adjacent groups of which may form a ring with each other. A7-A12 denote a hydrogen atom, alkyl group, alkoxy group, halogen atom, phenyl group, the adjacent groups of which may form a ring. Either one or both of A5 or A11 must be a phenyl group. The processing temp. of this photosensitive material is preferably ≤50°C, more particularly in a 30-40°C range.
