Abstract (en)
[origin: US4284708A] 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.
