Abstract: Organic photoconductive imaging receptors in which the charge transport layer contains, as a binder, a copolycarbonate of 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane and 2,2-bis-(4-hydroxylphenyl)propane exhibit excellent wear resistance.

Abstract: Metal sheet-thermoplastic resin laminate composites may be effectively separated into their component metal sheet(s) and thermoplastic resin sheet or core by first pressing the laminate composite through a pair of opposing rollers in which the roller(s) making contact with the metal surface(s) of the laminate composite is an embossing roller having projecting pins to obtain a laminate composite having a metal surface(s) with impressions and then heating the metal surface(s) of the laminate composite to separate the metal sheet(s) from the thermoplastic resin.
