Abstract: 1450906 Polyurethane layers; photopolymerizing unsaturated monomers BASF AG 3 Dec 1973 [4 Dec 1972] 55919/73 Headings C3R and C3P Polyurethane layers are prepared by adding a compatible monomer having at least two photocross-linkable C-C multiple bonds or a compatible monomer mixture comprising at least 50% by weight of one of such monomers and not more than 50% by weight of a photopolymerizable monoethylenically unsaturated monomer, and optionally also a photopolymerization initiator, to a liquid polyurethane elastomer forming reaction mixture comprising (A) (i) a polyether, polyester, hydroxypolyether urethane or hydroxypolyester urethane or a mixture thereof with a polyalcohol and/or a diamino and (ii) a diisocyanate or (B) (i) a prepolymer of a hydroxyl compound as defined in (A) and a diisocyanate and (ii) a polyester, polyether, hydroxypolyester urethane, hydroxypolyetherurethane, polyhydric alcohol, or diamine or a mixture of two or more thereof, the resulting mixture containing a major amount of the polyurethane elastomer-forming reaction mixture, applying the resulting mixture to a substrate to form a layer, irradiating the layer with electromagnetic radiation of wavelength less than 0À7 Ám to effect photocrosslinking of the monomer(s) and gelling of the layer and thermally curing the so-treated layer. The layer is suitably formed on a continuously moving substrate and has a thickness of from 0À2 to 5 mm. Conventional polyurethane elastomer-forming reactants are used. The monomer having at least two C-C multiple bonds is preferably an olefinically poly-unsaturated carboxylate, for example a diester of a C 2-6 aliphatic diol and acrylic or methacrylic acid, a triester of a C 3-10 aliphatic triol and acrylic or methacrylic acid, a divinyl ester of a C 2-8 dicarboxylic acid, a diallyl ester of a C 2-8 dicarboxylic acid and a vinyl ester or allyl ester of a C 3-5 olefinically unsaturated monocarboxylic acid. The unsaturated monomers are preferably used in amounts not exceeding 10% weight of the reaction mixture.

Abstract: Laminated plate for the prepn. of relief printing plates, as described in the parent patent, comprises a layer (I) of photoinitiator and opt. other conventional additives in a developer soluble photocrosslinkable compsn. (II), an underlayer (III) of a developer insoluble, non-photocrosslinkable elastomer having a Shore A hardness of 15-70 and a developer insoluble, non-photocrosslinkable stabilising layer (IV). In this addition (II) comprises >=1 soluble diblock copolymer (V) and >=1 photocrosslinkable unsatd. monomer. (V) comprises 75-85 wt. % 4-6C diene units of which >50 wt. % are isoprene units and 15-25 wt. % styrene units and has a viscosity of 150-250 ml/g (measured as a 5 wt. % soln. in toluene at 25 degrees C). The copolymer shows a sharp transition between the polystyrene segment and the polyisoprene segment and contains 4 wt. % homopolymer. (V) Can be easily synthesised in two steps, has good solvent and melt processability and can be cast or extruded to low tolerances of thickness.

Abstract: Laminates for the production of relief plates for flexographic printing, by imagewise exposure and washing out with a developer solution have, on a base optionally provided with an elastomeric layer, a photo-crosslinkable layer containing a photoinitiator and consisting of a polyurethane elastomer which has been prepared in a special manner from an aliphatic saturated polyesterglycol, an aliphatic diisocyanate, but-1-ene-3,4-diol and, if desired, another diol and which has a Shore A hardness of 30 to 90 DEG in the photo-crosslinked state, the elastomer being optionally mixed with a photo-crosslinked monomer.
