Process for the preparation of 2-cyano-3,3-diarylacrylates
 The preparation of 2-cyano-3,3-diarylacrylates I ##STR1## (in which Ar.sup.1 and Ar.sup.2 are aromatic radicals and R is an aliphatic radical having from 3 to 30 carbon atoms) by reacting a 2-cyano-3,3-diarylacrylate II ##STR2## (in which R.sup.1 is methyl or ethyl) with an alcohol III EQU R--OH (III) in the presence of a basic catalyst with removal of the alcohol R.sup.1 -OH formed. The esters of formula I are valuable UV absorbing agents for, say, plastics materials.
