Photoinitiator compounds comprising both a photoactive moiety and an amine functionality, bonded to a polyhedral oligomeric silsesquioxane, which photoinitiator is represented by formula (1) or (1') wherein n is 2m; m is an integer of 2 to 30; the sum of n' + a is an integer 4-60; n' is an even-numbered integer; a is an even-or uneven-numbered integer; and for example different A C1-C12alkyl, or a photoactive moiety Q1, or a group of formula (2); E for example is a direct bond, L is linear or branched C1-C3alkylene, preferably propylene; R1 and R2 for example are a photoactive moiety Q, or C2-20alkyl; Q is for example a group of formula (4); Z2 is for example C1-C6alkylene which is unsubstituted or substituted by one or more OR6; and R6, R12, R13 and R14 for example are hydrogen; are especially suitable as low-migrating photoinitiators.

[EN] This invention provides both metal carboxylates and tertiary ammonium carboxylates, in which carboxylates a benzoylphenyl group is present. Also provided are photoinitiator compositions which comprise a) (i) at least one metal carboxylate, in which carboxylate a benzoylphenyl group is present, and/or (ii) at least one tertiary ammonium carboxylate, in which carboxylate a benzoylphenyl group is present; and b) at least one coinitiator comprising at least one benzoyl moiety and at least one aliphatic alcohol moiety. Processes for photopolymerization with these photoinitiator compositions are also provided. [FR] Cette invention concerne à la fois des carboxylates de métaux et des carboxylates d'ammonium tertiaire, lesquels carboxylates comprennent un groupe benzoylphényle. L'invention concerne également des compositions de photoinitiateur qui comprennent a) (i) au moins un carboxylate de métal, lequel carboxylate comprend un groupe benzoylphényle, et/ou (ii) au moins un carboxylate d'ammonium tertiaire, lequel carboxylate comprend un groupe benzoylphényle ; et b) au moins un co-initiateur comprenant au moins une entité benzoyle et au moins une entité alcool aliphatique. L'invention concerne également des procédés pour la photopolymérisation avec ces compositions de photoinitiateur.
