Abstract

1,172,355. Photo-conductive materials. RENKER-BELIPA G.m.b.H. 12 Dec., 1966, No. 55586/66. Heading C3R. [Also in Division H1] An electrophotographic recording material comprises a layer of a photo-conductive reaction product formed by reaction between a compound containing at least one isocyanate group and a non-photo-conductive aryl heterocyclic or unsaturated aliphatic compound having at least one group capable of reacting with an isocyanate group. The photo-conductive layer may be produced before its application to a base or it may be produced from the reaction components on the base material directly. The base may be electrically conducting, semi-conducting or non-conducting. Conventional sensitizers may be added to the photo-conductive material as may photo-conductors of other kinds such as organic photo-conductors, photo-conductive pigments and photo-conductive metal compounds, particularly zinc oxide. Lists of numerous suitable compounds containing isocyanate groups and non-photo-conductive compounds containing groups capable of reacting with isocyanate groups are given. In a typical example, a solution was formed if N-diethyl-N- acetyl - p - phenylenediamine, cyclohexanone and an isocyanate prepared by reacting 1 mole of trimethylol propane with 3 moles of 2,4- or 2,6-toluylene diisocyanate and dissolved in ethyl acetate. The solution was boiled under reflux diluted with dioxane and acetone and used to coat an aluminium plate that had been anodically lustred. The layer was dried and was found to adhere well to the aluminium base. Other non-photo-conductive compounds containing groups reactive with isocyanate groups exemplified are anthranilic acid, mdimethylaminophenol, acetanilide, 2-methyl-4- nitro - 5 - chloro - aniline, p - bromo - acetanilide, N,N - dibenzoyl benzidine, N,N<SP>1</SP> - diphenyl-pphenylene diamine, ethyl-α-naphthylamine, ethyl - # - hydroxyethyl) aniline, m - diethylaminobenzoic acid and a reaction product of excess p-toluene sulphomethylamide and formaldehyde.
