Abstract: Disclosed is an electrophotographic recording material comprising a photoconductive double layer disposed on an electrically conductive support, which double layer comprises a charge carrier-generating layer and a charge transport layer. The interface region of the charge carrier-generating and charge transport layers defines a mixing zone into which one or more of the constituents of the separate layers have diffused. A process for producing the electrophotographic recording material is also disclosed.

Abstract: Copolymers (I) of olefinic monomer(s) comprise an isomeric mixt. of esters of isobornyl alcohol with an alpha , beta -unsatd. acid. The isomeric alcohol mixt. contains: (a) not more than 92% isoborneol, (b) at least 3.5% iso-fenchyl alcohol, and (c) at least 1% pseudo-bornyl alcohol. Also claimed are: (i) a process for the prodn. of (I) by bulk polymerisation in the presence of aliphatic azo cpds., diacyl peroxide, alkyl per-esters, alkyl hydroperoxide, dialkyl peroxide or peroxy-di-carbonate as radical initiators; and (ii) a process for the prodn. of water-dilutable polyacrylate dispersions by: (A) dissolution of (I) in a water-dilutable organic solvent, followed by: (B) partial or complete neutralisation, and (C) dilution by adding water or stirring the soln. into water.

Abstract: An electrophotographic recording material is described for preparing a printing form or a printed circuit, comprising a layer support and a photoconductive layer comprised of photoconductor, sensitizer and/or activator, if appropriate further additives which improve surface texture and/or adhesion and a high molecular weight binder which is soluble in an alkaline aqueous or alcoholic solution and the photoconductive layer of which recording material contains as binder the product of reacting a sulfonyl isocyanate of the general formula R-SO2-NCO in which R is alkenyl having up to 4 carbon atoms or phenyl which can be substituted by alkyl having up to 3 carbon atoms, with a hydroxyl-containing polymer in a molar ratio within the range of (0.5 to 1):1.
