  • Vinyl-ester polymeric timing layer for color transfer assemblages
    Patent number: 4480080
    Abstract: Photographic assemblages, elements, receiving elements and cover sheets are described employing a novel timing layer comprising the following recurring units: ##STR1## wherein R.sup.1 is a straight or branched chain alkyl group of from 1 to about 10 carbon atoms or aralkyl group of from about 7 to about 10 carbon atoms;R.sup.2 is a substituted or unsubstituted aryl group of from 6 to about 12 carbon atoms;R.sup.3 is a straight or branched aliphatic group having from 1 to about 20 carbon atoms or an aromatic group having from about 6 to about 20 carbon atoms, the group being substituted with at least one free carboxylic acid group, free sulfonic acid group, free phosphoric acid group or salt thereof;x is from about 1 to about 30 weight percent; andy+z is from about 99 to about 70 weight percent, the ratio of y:z ranging from about 15:85 to about 70:30.The timing layer has a high activation energy and provides improved processing temperature latitude.
    Type: Grant
    Filed: October 24, 1983
    Date of Patent: October 30, 1984
    Assignee: Eastman Kodak Company
