PURPOSE:To obtain an excellent irradiation and halation preventive effect by providing a hydrophilic colloidal layer contg. a specific dye. CONSTITUTION:The hydrophilic colloidal layer contg. the dye expressed by the formula I is provided. In the formula I, R1, R2 denote a substd. or unsubstd. alkyl group {1 to 5C lower alkyl group (for example, methyl group, ethyl group, propyl group, butyl group, etc.)} Z<1> and Z<2> denote a nonmetal atomic group necessary for forming a benzo condensed ring; R3 denotes sulfur or -C(CH3)2-; L denotes a substd. or unsubstd. methyne group. The photosensitive material having the irradiation and halation preventive effect is obtd. |
