ABSTRACT:
Disclosed herein are heat-activatable adhesive compositions comprising a water-soluble condensation polymer which is characterized by having a glycol component comprising one or more diols, preferably one of which is 1,4-bis(2-hydroxy-ethoxy)cyclohexane; and an acid component comprising greater than 15 and up to about 35 mole percent of at least one diacid or diester monomer having an iminodisulfonyl salt moiety, and from about 65 to about 85 mole percent of one or more other diacids or diesters. These adhesives are further characterized as having high bonding strengths at temperatures above 50.degree. C. They have been found useful in a variety of photographic materials, and particularly in image transfer film units.
