    摘要: A protective overcoating layer for an electrophotographic imaging device prevents crystallization and leaching of hole transport compounds in a charge transport layer of the imaging device. The overcoat also prevents solvent and ink contact/bending stress charge transport layer cracking. The overcoating layer contains a polyester homopolymer which contains a hole transporting compound and an aliphatic diol in the polymer chain backbone. The homopolymer can be either a meta or para hole transport compound ester linkage polyester homopolymer.

    摘要: Polyamides, particularly aromatic polyamides and mixed aromatic-aliphatic polyamides, are produced by heating various amidines or amidine derivatives to yield polymer and a volatile low molecular weight amide, such as formamide. The thermally polymerizable composition is an aromatic amidine or salt thereof, e.g. N,N-1,4-phenylene bis-(N',N'-dimethylformamidinium) terephthalate which is heat polymerizable to poly-(p-phenylene terephthalamide); or N-(p-carboxyphenyl)-N',N'-dimethyl formamidine hydrochloride which is heat polymerizable to poly-(p-benzamide).
