| titleOfInvention | Water-dispersible polyester adhesives for photographic materials |
| abstract | Abstract of the Disclosure Disclosed herein are heat-activatable adhesive compositions containing a water-dispersible polyester which comprises A. an acid component comprising: (1) from about 8 to about 16 mole percent of units derived from at least one dicarboxylic acid hav-ing an ionic iminosulfonyl moiety containing a monovalent cation as an imino nitrogen sub-stituent; (2) from about 40 to about 70 mole percent of units derived from at least one dicarboxylic acid selected from the group consisting of aliphatic dicarboxylic acids having the formula HOCC-(CH2)n-COOH wherein n is an integer from 2 to 12, cycloaliphatic dicarboxylic acids having from 6 to 12 carbon atoms, and aromatic dicarboxylic acids having from 6 to 12 carbon atoms; (3) from about 5 to about 20 mole percent of units derived from the dicarboxylic acid having the formula (4) from about 5 to about 25 mole percent of units derived from at least one dicarboxylic acid hav-ing the formula wherein Z is carbonylimino or iminocarbonyl and m -ii-B. a diol component consisting essentially of (1) at least 50 mole percent of units derived from at lease one diol having a formula selected from the group consisting of (I) wherein p is an integer from 1 to 4, and (II) HO-(RO)q-H wherein q is an integer from 2 to 4; and R is an alkylene group having from 2 to 4 carbon atoms; and (2) from 0 to 50 mole percent of units derived from at least one diol having the formula: HO-R'-OH wherein R' is an alkylene group having up to 16 carbon atoms, cycloalkylene having from 6 to 20 carbon atoms, cycloalkylenebisalkylene having from 8 to 20 carbon atoms, or arylenebisalkylene having from 8 to 20 carbon atoms with the proviso that said diol component (1), selected from the group consisting of (1) and (II), must comprise at least 90 mole percent of the diol component when said acid component (1), having an ionic iminosulfonyl moiety, comprises less than 10 mole percent of said acid component. These adhesives have been found useful in a variety of photographic materials, and particularly in image transfer film units. Their Adhesive strength is further charac-terized as being insensitive to variations in relative humidity and, after being dried, to the presence of aqueous processing compositions. |
