    Abstract: 1,148,328. Photo-polymerization process. BADISCHE ANILIN- & SODA-FABRIK A.G. 22 July, 1966 [23 July, 1965], No. 33012/66. Heading C3P. [Also in Division G2] A photographic process for the production of printing plates comprises image-wise exposing a photo-polymerizable material in the form of a plate or sheet and containing 80 to 40% by weight of a synthetic linear polyamide, 0À5 to 15% by weight based on the polyamide of benzene-sulphonic acid n-butylamide, 20-60% by weight of monomer(s) containing at least one monomer having at least two polymerizable double bonds and optionally at least one monomer with a single double bond, the single double-bond monomer content being up to 40% of the total monomer content, and a photo-initiator (e.g. benzoin methyl ether) and then developing the exposed material. A polymerization inhibitor may also be present in the composition of the layer. Exemplified monomers with at least two double bonds are alkylene and arylene bisacrylamides; 4,4 1 -bis-(acryloylamino cyclohexyl)-methane and triallyl cyanurate, while styrene, maleic anhydride, methyl methacrylate and butane diol-(1,4)-monoacrylate are exemplified as monomers with single double bonds.

    Abstract: 3-N-acetoxyethylanilino-propine-1 is prepared by reacting beta-hydroxyethylaniline with propargyl chloride to give 3-betahydroxyethylanilino-propine-1 and reacting this with acetyl chloride. 3-N-betahydroxyethylanilinobutine-1 is obtained from N-beta-hydroxyethylaniline and 3-chloro-butine-1.ALSO:The invention comprises p-aminoazo dyes of formula wherein A is an aromatic or heterocyclic diazo radical which contains at least one alkyl, alkoxy, nitro, sulphonamide, alkylsulphonyl, acylamino, cyano or trifluoromethyl group or halogen atom but no carboxylic or sulphonic acid groups, B is the radical of an azo component free from carboxylic or sulphonic acid group, R1 is a radical which between the amino and acetylene groups contains 1-4 aliphatic carbon atoms some of which may be replaced by hereto atoms, which radical may also be further substituted and R2 and R3 are hydrogen or aliphatic radicals. The dyes are prepared by normal diazotization and coupling procedures using suitable components. The dyes may be used to colour fibres and other materials of acetyl-cellulose, polyamides, polyurethanes, polycarbonates and polyacryonitriles in orange, red and violet shades. In an example 4-nitroaniline is diazotized and coupled with 3-N-acetoxyethylanilino-propine-1 (see Group IV(b)). Further examples are specified.
