Abstract
The present invention relates to a flexible electrostatographic imaging member. The electrostatographic imaging member contains an optically transparent thermoplastic anti-curl back coating, which enables the imaging member to maintain desirable structural flatness, mechanical robustness, flexibility, longevity, and copy image qualities over extended use. The present invention also relates to a process of fabricating a flexible electrostatographic imaging member.
Claims42
A flexible electrostatographic imaging member comprising:
- a substrate support having a first and a second major surface;
- a multilayered photoimaging layer on the first major surface of the substrate support;
- and
- an optically transparent anti-curl back coating on the second major surface of the substrate support, said anti-curl back coating comprising a film forming thermoplastic polymer and having a glass transition temperature (Tg) value of at least about 75° C., a thermal contraction coefficient value of at least about 1.5 times greater than the thermal contraction coefficient value of the substrate support, a Young's Modulus of at least about 2×105 pounds per square inch (p.s.i.), and a 180° peel strength value of at least about 15 grams/centimeter (g/cm).
