Abstract

A mixture of acrylic or methacrylic compounds, containing from 40 to 95% by weight, based on the total amount of the acrylic or methacrylic compounds, of epoxide (meth)acrylates, is obtainable by a process comprising the process steps PA1 a) esterification of hydroxy compounds with acrylic acid or methacrylic acid, PA1 b) if required, subsequent addition of further acrylic acid or methacrylic acid and PA1 c) subsequent reaction of the excess acrylic or methacrylic acid with epoxides in the presence of the esterification product of a).
