Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein perylene-3,4,9,10-tetracarboxylic acid N,N'-bis-(2',6'-dichlorophenyl)-diimide is employed as the charge carrier-producing dye, and the production of this recording medium.

Abstract: Photopolymer relief plates are produced by applying a photopolymerizable relief-forming layer R, which contains a thermal polymerization inhibitor liberating nitrosyl free radicals on ultraviolet irradiation, to a dimensionally stable base which bears an adhesive layer A for the layer R, the layer A containing 0.01 to 10 percent by weight of a compound where R1, R2, R3 and R4 are identical or different and each is alkyl or R5-(O-alkylene)x-, R5 being H or alkyl and x being 1, 2, 3, 4 or 5, and then exposing, and developing, the layer R in a conventional manner.

Abstract: A photopolymerizable recording composition which comprises a mixture, containing a photoinitiator, of (a) a photopolymerizable olefinically unsaturated monomer and (b) an organic polymeric binder, wherein the photoinitiator is an acylphosphine oxide compound of the formula R1R2PO-CO-R3, where R1 and R2 are certain organic radicals and R3 is tert.-alkyl or a cyclic radical with two substituents in the ortho-position to the carbonyl group. The recording compositions have a high reactivity when irradiated with UV light and are used in particular for the preparation of printing plates, relief plates and photo-resists.

Abstract: Photopolymerizable compositions for the production of printing plates and relief plates, consisting essentially of a photoinitiator-containing mixture of olefinically unsaturated photopolymerizable compounds with polymeric binders, contain up to 1% by weight of a compound having the structural element of anthrone, e.g. bianthrone and 9,9'-bianthryl, which results in an improved relief image in the production of relief plates.

Abstract: 1519059 Photo-crosslinkable polyurethane composition BASF AG 12 Sept 1975 [13 Sept 1974] 37561/75 Heading C3V A photo-crosslinkable composition comprises a photoinitiator and a mixture of the following materials in the proportions:-(A) from 40 to 80% by weight of an olefinically unsaturated isocyanate group-free polyurethane which has a molecular weight of from 400 to 10,000 and which has been manufactured by reaction of (A1) a polyester having a hydroxyl number of 100 to 300 and derived from a C2 to C8-saturated polyhydric aliphatic alcohol and a C4 to C8- saturated dicarboxylic acid, or an ester forming derivative of such dicarboxylic acid, at least 50 mole per cent of such polyester-forming materials being saturated aliphatic compounds with (A2) a C6 to C36-polyisocyanate and (A3) a monoacrylate or monomethacrylate of a C2 to C10- aliphatic diol and (B) from 60 to 20% by weight of a C6 to C8-N-vinyl lactam-monomer or a mixture of at least 20% by weight thereof with at least one comonomer, or with a reaction product prepared from (A2) and (A3). Examples are given in which (a) an adipic acid/phthalicanhydride/1,2 -propylene glycol/1,1,1-trimethylolpropane polyester is reacted with hexamethylene diisocyanate and 2-hydroxypropyl acrylate, the product being mixed with N- vinylpyrrolidone and benzoin methyl ether, applied to a substrate and exposed image-wise to UV light to form a relief printing plate; (b) as (a) except that a monomer mixture (B) of N - vinylpyrrolidone, 1 - hydroxypropyl acrylate, 2 - hydroxypropyl acrylate and acrylamide is used; (c) a polyester as in (a) is reacted with isophorone diisocyanate, 2-hydroxypropyl acrylate and, optionally, 1 - hydroxypropyl acrylate, mixed with N-vinylpyrrolidone or a mixture thereof with 2-hydroxypropylacrylate and acrylamide, and used as in (a), using benzoin isopropyl, or methyl ether as initiator.
