1285619 Photoconductive compounds CANON KK 30 Dec 1969 [30 Dec 1968 12 May 1969] 63282/69 Heading C4P [Also in Division H1] Examples 1-11 and 17-29 describe the preparation of photoconductive compounds which have dyestuff structures by the condensation of an amino or hydroxyl group containing compound with a reactive halogen containing compound so as to form a covalent bond between the reactants. The starting materials include a hydroxy or amino derivative of a hydrocarbon, an anthraquinone, an acridine, a carbazole, an oxazole, an oxadiazole, a thiazole, an imidazole or polyacenaphthalene, an acid chloride of a carbazole, an amino or dichlortriazine derivative of a diazo component, an anthraquinone or a pyrazolone
