    • 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.

    • Disclosed herein are heat-activatable adhesive compositions comprising an amorphous condensation polymer which is characterized by having an acid component comprising a phthalic acid derivative and a glycol component comprising from about 15 to about 85 mole percent of (1) a linear aliphatic glycol having the structure HO--R--H wherein R is either: ##STR1## or --CH.sub.2 CH.sub.2 O--.sub.n wherein n is an integer from 2 to 4; and from about 85 to about 15 mole percent of (2) a branched aliphatic glycol having the structure: ##STR2## wherein R.sup.1 and R.sup.2 are alkyl. These polyester adhesives are further characterized as being soluble in halogenated solvents, having glass transition temperatures within the range of about -30.degree. C. to about 50.degree. C., and having high bonding strengths at elevated temperatures. They have been found useful in a variety of photographic materials, and particularly in photographic film units.
