Radiation curable acrylates incorporating photoinitiators

摘要

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<1> (II) R = 1-4 C alkyl, aryl or R<1>; R<1> = a substd. phenyl gp. of formula (IV); R<2> - R<6> = 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<2> - R<6> 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..
