ABSTRACT:
An imaging element is described comprising a support material having thereon at least one image-forming layer and at least one layer coated from a composition containing a dispersion of aqueous dispersible polyurethane polymer particles dispersed in a continuous liquid phase comprising primarily water-miscible organic solvent. A coating composition for coating a polyurethane layer on a moving film support is also described comprising a dispersion of aqueous dispersible polyurethane polymer particles dispersed in a continuous liquid phase comprising primarily water-miscible organic solvent, said composition having a concentration of from 0.1 to 20 wt percent total solids and a viscosity of from 0.5 to 50 centipoise. The coating compositions in accordance with this invention have unique coating rheologies and provide layers for imaging elements having excellent film forming and physical and mechanical properties.
