ABSTRACT:
A coating composition that is useful for the preparation of an auxiliary layer of an imaging element, such as a photographic element, is comprised of an aqueous medium having dispersed therein film-forming polymeric particles and non-film-forming polymeric particles and is characterized in that the film-forming polymeric particles are acid-stable polyurethane particles. These coating compositions have excellent stability characteristics, provide auxiliary layers with improved chemical and physical properties when coated and dried to form a coalesced layer, and provide for reduced emission of volatile organic compounds during the drying process.
