摘要 Compounds of formula (I) {where n is a number from 1 to 6; R<3> is hydrogen, methyl or ethyl; A represents a group of formula -[O(CHR<2>CHR<1>)a]y-, -[O(CH2)bCO]y-, or -[O(CH2)bCO](y-1)-[O(CHR<2>CHR<1>)a]- (where one of R<1> and R<2> is hydrogen and the other is hydrogen, methyl or ethyl); a is from 1 to 2; b is from 4 to 5; y is from 3 to 10; Q is a residue of a polyhydroxy compound having 2 to 6 hydroxy groups; and x is greater than 1 but no greater than the number of available hydroxyl groups in Q} and esters thereof are useful as photoinitiators for the preparation of energy-curable compositions, such as varnishes and printing inks.
