摘要： Novel photographic products for use in color diffusion transfer, particularly color diffusion transfer systems for forming color images viewable without separation as reflection prints, which products include a neutralizing layer for lowering the environmental pH after application of an aqueous alkaline processing fluid and a ''''timing'''' spacer layer so disposed with respect to the neutralizing layer that the processing fluid must first diffuse through the spacer layer before contacting the neutralizing layer, the spacer layer comprising, as a continuous phase, the coalesced essence of an aqueous film-forming synthetic polymer dispersion which is substantially impermeable to the processing fluid and a discontinuous phase comprising a material which is permeable to the processing fluid.

摘要： PROBLEM TO BE SOLVED: To obtain a color photosensitive material which has excellent dependence on the treatment temp., which does not require complicated control for the coating and drying facilities, and which can be controlled for timing with an easily available material, by incorporating a neutralizing element consisting of a neutralizing layer and a timing layer, and incorporating acetylcellulose and a specified compd. into the timing layer. SOLUTION: This photographic sensitive material has a photosensitive element, a neutralizing element consisting of a neutralizing layer and a timing layer to decrease the pH of an alkali treating compsn., and an alkaline treatment compsn. which is spread between the photosensitive element and the neutralizing element and which has an image accepting layer to fix dyes to at least one element of the photosensitive element and the neutralizing element. The timing layer contains acetylcellulose and at least one kind of' compd. expressed by formula I or formula II: R1-COO-R2. In the formulae, each of R1 to R3 is an alkyl group, cycloalkyl group, alkenyl group, aryl group or the like and may be same or different, but does not form a copolymer.

SOLUTION: A light-shielding type alkali treating liquid compsn. is spread between a photosensitive sheet and a transparent cover sheet having a neutralizing layer. The neutralizing layer contains a copolymer having 5.0×10 to 3.0×10 weight average mol.wt. and comprising repeating units expressed by formula II and repeating units derived from acrylate. The alkali treating liquid compsn. contains repeating units expressed by formula I by 30 to 70wt.% and repeating units expressed by formula II by 5 to 25wt.%. In formulae, R11 , R21 are hydrogen atoms or alkyl groups, R12 and R13 are alkyl groups, etc., L1 , L2 are bivalent connecting groups, n1 , n2 are 0 or 1, and M is a hydrogen atoms or alkali metal atom.
