PURPOSE:To provide high water solubility together with a rapid curing effect to photograph constituting layers and to prevent a coating liquid from thickening when a specific compd. is added to the coating liquid by curing at least one layer of the above-mentioned layers by the above-mentioned compd. CONSTITUTION:At least one layer of the photograph constituting layers formed on a base are cured by the compd. expressed by formula I. In formula I, A denotes an org. group of n valency having at least one hydroxyalkyl group as a substituent; R denotes 1 to 4 hydrocarbon, hydrogen atom or CH2=CHSO2 CH2CH2CO-; n denotes 2, 3 or 4. The sufficient film strength is assured in this way without impairing photographic characteristics and there is no post film curing effect. The film has an excellent adhesive property to the base and even if the compd. is added to the emulsion, the emulsion does not thicken and is imparted with sufficient water solubility. |
