Abstract: A polyurethane which is substantially self-dispersible in water and is obtainable by reacting a) at least one polyisocyanate with b) at least one polyol and c) at least one photoinitiator of the general formula I (see fig. I) where R is a radical of the formula II (see fig. II) or is -CR7R8R9, P(=O)(R10)2 or SO2R11, the number-average molecular weight Mn of the polyurethane being greater than 2700, and its use. The invention also relates to aqueous polyurethane resin dispersions and coating compositions comprising the novel polyurethanes, and to their use.

Abstract: PCT No. PCT/EP95/04576 Sec. 371 Date May 23, 1997 Sec. 102(e) Date May 23, 1997 PCT Filed Nov. 21, 1995 PCT Pub. No. WO96/02597 PCT Pub. Date Feb. 1, 1996A process for coating or printing substrates with a coating or printing composition comprises applying a polymerizable material containing liquid-crystalline, polymerizable monomers which carry at least two polymerizable groups for coating and at least one polymerizable group for printing, to the substrate, and subsequently carrying out the polymerization, where the coating composition or the printing composition comprises a1) a chiral liquid-crystalline monomer and b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), or the coating composition or the printing composition comprises a2) an achiral liquid-crystalline monomer, b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), and c) a non-liquid-crystalline chiral compound.

Abstract: The invention relates to a light-sensitive recording material for producing intaglio printing plates and to a process for producing intaglio printing formes. … The photopolymerisable and/or photocrosslinkable material, which is soluble or dispersible in a developer fluid and becomes insoluble or no longer dispersible in this developer fluid by exposure to actinic light, contains, at least in a surface zone of the surface of the layer which later forms the surface of the printing forme, finely disperse abrasive particles, the mean particle size of the abrasive particles being in the range from 0.1 to 6 mu m, the abrasive particles having a hardness of >4.0 on the Mohs hardness scale, the surface of the layer which later forms the surface of the printing forme having a peak-to-valley height of
