Abstract
An imaging member has a substrate of a polymer insoluble in solvent for the charge transport layer, a Tg of at least 90.degree. C. and a linear thermal contraction coefficient substantially identical to the linear thermal contraction coefficient of a charge transport layer.
Claims18
An electrostatographic imaging member comprising a substrate and a charge transport layer applied by solution coating in methylene chloride;
- said substrate being comprised of a polymer selected from the group consisting of polyamide/nylons, polycarbonate/polybutylene terephthalate alloys, polyphthalamides, polyester liquid crystals, phenolic polymers and diallyl phthalates, said polymer insoluble in the methylene chloride and having a T.sub.g of at least 90.degree. C. and a linear thermal contraction coefficient within about plus or minus 2.times.10.sup.-5 /.degree.C. of the thermal contraction coefficient of said charge transport layer.
An electrostatographic imaging member comprising a substrate and a charge transport layer applied by solution coating in methylene chloride;
- said substrate being comprised of a polymer subjected to gamma ray irradiation to provide a form insoluble in said methylene chloride and having a T.sub.g of at least 90.degree. C. and a linear thermal contraction coefficient within about .+-.2.times.10.sup.-5 /.degree.C. of the thermal contraction coefficient of said charge transport layer.
