摘要：
The present invention describes an imaging element wherein one layer is coated from an aqueous coating solution having a film forming binder. The film forming binder includes a carboxylic acid containing vinyl polymer or copolymer having a glass transition temperature greater than 60.degree. C. and an acid number of from 60 to 260. The carboxylic acid groups of the vinyl polymer or copolymer are reacted with ammonia or amine to provide a pH of the coating composition of from about 7 to 10.
