Compounds of formula (I): [where: the substituents R1 are individually selected from C1 - C10 alkyl groups and optionally substituted benzyl groups; the substituents R2 are individually selected from alkyl groups or, together with the nitrogen atom to which they are attached, represent a nitrogen- containing heterocyclic group; Z is selected from C6 - C10 arylene groups and groups of formula -(CHR3)n- , where R3 is hydrogen, hydroxy or a C1 - C4 alkyl group, and n is 0 to 6; Y is carbonyl or -CH2-; Q is a residue of a mono- or poly-hydroxy compound; and x is 1 to 6; and esters thereof] are useful as multi -functional photoinitiators for use in coating compositions to be cured by radiant energy.

L'invention concerne des composés de la formule (I), [dans laquelle les substituants R1 sont indépendamment choisis dans les groupes C1-C10 alkyle et les groupes benzyle éventuellement substitués; les substituants R2 sont indépendamment choisis dans les groupes alkyle ou, ensemble avec l'atome d'azote auquel ils sont liés, représentent un groupe hétérocyclique contenant de l'azote; Z est choisi dans les groupes C6-C10 arylène et les groupes de formule (CHR3)n-, R3 représentant hydrogène, hydroxy ou un groupe C1-C4 alkyle, et n un entier compris entre 0 et 6; Y représente carbonyle ou CH2-; Q représente un résidu d'un composé mono ou polyhydroxy; et x est compris entre 1 et 6; ainsi que des esters associés]. Lesdits composés servent de photoinitiateurs multifonctionnels utilisés dans des compositions de revêtement à durcir par énergie rayonnante.
