ABSTRACT:
Photoconductive polycarbonate block copolymers are provided containing alternate polycarbonate blocks and photoconductor blocks. The photoconductive blocks are copolymers of polyesters and/or polycarbonates with reactive photonconductors which are preferably difunctional polyols and/or carboxylic acid derivatives. The block copolymers when blended with dyes form photoconductive layers in photoconductor elements which are photosensitive and highly resistant to solvent degradation. Dyes are aggregatable in such a block copolymer matrix.
