摘要： Photographic assemblages, elements, receiving elements and cover sheets comprise a combination of two timing layers and a neutralizing layer. The outermost timing layer contains photographic addenda, such as development inhibitors, for substantially terminating development of the silver halide emulsion. The timing layer next to the neutralizing layer has a much longer breakdown time so that it is permeated by the alkaline processing composition only after silver halide development has been substantially terminated.

摘要： Two-sheet diffusion transfer assemblages and photographic elements are described which contain a primer layer located between a polymeric acid layer and a timing layer. The primer layer prevents unwanted transfer of portions of the emulsion layer to the receiver when the receiver and photographic element are peeled apart. The primer layer comprises:(a) a mixture of gelatin and cellulose nitrate, or(b) a mixture of an acrylic acid copolymer and a particular acrylic acid terpolymer, or(c) an acrylic acid copolymer as described herein.

摘要： A photographic film unit for the production of colored transfer images contains an integral neutralization system consisting of an acid polymer layer and a retarding layer. The acid polymer layer consists of a copolymer of 5 to 50 % by weight of polymerized carboxyalkyl (meth)acrylate units together with other acid monomers and optionally nonacid monomers. A preferred carboxyalkyl (meth)acrylate is the dimeric acrylic acid. The acid polymer has high acid number and low glass transition temperature.
