PURPOSE:To enable an exposing process using an argon laser scanner to be operated in a light room by incorporating silver halide grains composed of silver chloride formed in the presence of a specified compound, and another specified compound in a silver halide emulsion layer formed on a support. CONSTITUTION:At least one silver halide emulsion layer formed on a support contains the silver halide grains composed of >=50mol% silver chloride formed in the presence of the compound represented by formula I and the compound represented by formula II, and in formulae I and II, Z is a nonmetallic atomic group necessary to form a hetero ring; X is H or the like; R1 is alkyl; each of Z1 and Q is a nonmetallic atomic group; and m is 1 or 2, thus permitting the exposure process using the argon laser scanner to be operated in the light room, and the obtained photosensitive material to be enhanced in sensitivity to the argon laser beams. |
