Vinylidenchlorid enthaltende Beschichtungs-Zusammensetzung für Bildaufzeichnungs-Elemente

摘要

The present invention describes an imaging element having a support, an image forming layer and at least one layer formed from an aqueous coating composition containing a film forming binder. The film forming binder is an interpolymer containing carboxylic acid groups. The interpolymer contains from 60 to 90 weight percent vinylidene chloride. The interpolymer has an acid number of from 30 to 150 and the carboxylic acid groups are reacted with ammonia or amine so that the aqueous coating composition has a pH of from 7 to 10.
