Abstract
1275663 Photoconductive recording material BELL & HOWELL CO 28 Aug 1969 [3 Sept 1968] 42767/69 Heading H1K [Also in Division B6] A recording element comprises a photoconductive layer 15 between electrodes 13 on a glass support 12 and having a layer 18 of magnetizable particles in heat-transfer relationship with the photoconductive layer. The magnetizable particles have a relatively low Curie point e.g. chromium dioxide whose Curie point is 100‹ C. In alternative embodiments the photoconductive and the magnetizable layer may be contiguous without an intervening electrode (Fig. 3, not shown) or a composite layer (50) of photoconductive and magnetizable materials may be used (Fig. 5, not shown). In the latter embodiment the magnetizable particles may each be encapsulated by an insulating layer to prevent them shunting out the photoconductive particles.
