Imaging elements having a layer formed from an aqueous coating composition comprising film forming binder and non-film forming polymeric particles

摘要

The present invention is an imaging element which includes a support and at least one layer formed from, (A) film forming binder, and (B) non-film forming polymeric particles. The film forming binder is formed from a coating solution of carboxylic acid containing vinyl polymer or copolymer having a glass transition temperature of greater than 50 DEG C and an acid number of 60 to 260, the carboxylic acid containing vinyl polymer or copolymer is reacted with ammonia or amine so that the coating solution has a pH of from 7 to 10.
