Radiation-curable (meth) acrylates, obtainable by reacting compounds of the formula where R is a C 1 -C 4 alkyl radical, an aryl radical or the radical R 1 and R 1 for the rest stands, wherein the radicals R 2 to R 6 independently of one another H, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, OH, phenyl, SH, SCH 3 , SC 2 H 5 , F, Cl, Br , CN, COOH, COO- (C 1 -C 17 alkyl), COO- (C 5 -C 10 aryl), CF 3 , N (alkyl) 2 , N ((alkyl) (aryl), N (aryl ) 2 , N ⊕ (alkyl) 3 A ⊖ , N ⊕ (alkyl) 2 A ⊖ , A ⊖ the anion of an acid and alkyl or aryl, unless stated otherwise, a C 1 -C 10 alkyl group or a C 5 -C 10 aryl group and at least one, but a maximum of 3 of the radicals R 2 to R 6 is a group are, with hydroxy (meth) acrylates, which contain at least 1 free hydroxy group and at least 2 (meth) acrylic groups in the molecule. |
