    Abstract: Radiation-curable (meth)acrylates (I) are claimed, which are obtd. by reacting: (i) acylphenyl chloroformates of formula (II) with: (ii) hydroxy (meth)acrylates (III) contg. free hydroxy gp(s). and (meth)acryl gps. in the molecule: R-C(=O)-R (II) R = 1-4 C alkyl, aryl or R ; R = a substd. phenyl gp. of formula (IV); R - R = H, 1-4 C alkyl, 1-4 C alkoxy, OH, phenyl, SH, SCH3, SC2H5, F, Cl, Br, CN, COOH, COO-(1-17 C alkyl), COO-(5-10 C aryl), CF3, N(alkyl)2, N(alkyl)(aryl), N(aryl)2, N , or N H(alkyl)2A ; A = an anion; alkyl, aryl = 1-10 C alkyl and 5-10 C aryl, unless otherwise indicated; and 1-3 R - R gps. = -O-C(=O)-Cl. Also claimed are: (a) a process for the prodn. of radiation curable (meth)acrylate; and (b) use of radiation curable (meth)acrylate in radiation curable compsns..

    Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.

    Abstract: A radiation curable polyurethane composition contains an aliphatic urethane group comprising a pre-polymer having two ethylenically unsaturated double bonds per molecule and a monofunctional ester of an alpha , beta -unsaturated carboxylic acid having a saturated 5-6C ring or heterocyclic ring. A radiation curable composition (I) contains: (A) an aliphatic, urethane group containing pre-polymer having on average, two ethylenically unsaturated double bonds per molecule; (B) a monofunctional ester of an alpha , beta -unsaturated carboxylic acid with a monofunctional alcohol, that has a saturated 5-6 membered carbon ring or heterocyclic ring comprising 1-2 oxygen atoms; and optionally (C) a di- or poly-functional ester of an alpha , beta -unsaturated carboxylic acid with an aliphatic di- or polyol. An Independent claim is included for a coating process of substrates by applying (I) to a substrate, optionally removing a solvent and irradiating with UV or an electron beam.

    Abstract: Prodn. of radiation-hardenable acrylate compsns. comprises: (i) the addn. of a cpd. (A) contg. acrylic gps. to a non-radically copolymerisable benzophenone deriv. contg. prim. or sec. amine gp(s), or OH gp. or mercapto gp.. Also claimed are: (1) radiation hardened materials contg. radiation hardenable acrylate compsns.; (2) benzophenone derivs. of formula RCOR (I) as novel cpds.; and (3) prepn. of the novel cpds. (I). R = phenyl or R ; R = a gp. of formula (II); and R -R = H, 1-4C alkyl or 1-4C alkoxy, with 1-3 of gps. R -R being a 1-30C organic gp. (X) with a prim. or sec. amine gp., OH gp. or mercapto gp..
