PURPOSE: To improve the color formability and dye image preserving property of a photosensitive material by incorporating a specific high boiling org. solvent into photograph constituting layers.

CONSTITUTION: The high boiling org. solvent expressed by the formula I and/or II is incorporated into ≥1 layers of the photograph constituting layers on a base (e.g., polyethylene coated paper). In the formulas, R1, R4 denote alkyl, alkenyl, aryl, etc., R2, R3, R6, R7 denote alkylene, alkenylene, cycloalkylene, etc., R5, R8 denote acyl, phosphonyl; n denotes 1W20. The above-mentioned org. solvent may be added to either of a photosensitive layer and non- hotosensitive layer and may be used in conjunction with the other high boiling org. solvent. The photosensitive material which maintains the initial gloss even after preservation under high humidity and has the excellent color formability and light resistance is thus obtd.
