Abstract
A photosensitive material in which a fog unnecessary for a photosensitive material is not generated when irradiation of a laser beam and a character or a mark is printed by an array of optically distinguishable dot patterns is provided. When the dot patterns are arrayed by M number in column and N number in row and the character or the mark having a size of A×B is printed, the dot pattern has irregularity of no more than S+10 μm, and an almost circular shape of no lower than 100 μm and not more than the smaller diameter either A/M or B/N, when viewed from the emulsion layer side. A surface roughness is set in the range of 0.2 μm to 1.0 μm.
