Abstract:
A composition comprisinga) at least one ethylenically unsaturated monomer or oligomer b) a radical initiator which forms a radical upon heating or upon irradiation with (UV) light from 305 nm to 450 nm and c) a compound of formula (Ia), (Ib) or (Ic) â€ƒwherein Y is a group which activates the double bond towards Michael addition; X is halogen or the anion of a mono carboxylic acid from 1-12 carbon atoms, a monovalent oxo acid or complex acid; n is 0 or 1; R1, R2 R3 are independently of each other hydrogen, unsubstituted C1-C18alkyl, C3-C18alkyl, interrupted by at least one nitrogen or oxygen atom, C3-C18alkenyl, C3-C18alkynyl, C7-C9phenylalkyl, C3-C12cycloalkyl or C3-C12cycloalkyl containing at least one nitrogen or oxygen atom; or C1-C18alkyl or C3-C18alkyl interrupted by at least one nitrogen or oxygen atom, C3-C18alkenyl, C3-C18alkynyl, C7-C9phenylalkyl, C3-C12cycloalkyl or C3-C12cycloalkyl containing at least one nitrogen or oxygen atom, which are substituted by NO2, halogen, amino, hydroxy, cyano, carboxy, C1-C4alkoxy, C1-C4alkylthio, C1-C4alkylamino, C1-C4alkylamino, di(C1-C4alkyl)amino or by a group â€”Oâ€”C(O)â€”C1-C8alkyl; or phenyl, naphthyl, which are unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, C1-C4alkylthio, halogen, cyano, hydroxy, carboxy, C1-C4alkylamino or di(C1-C4alkyl)amino; or R1 and R2, together with the linking hetero atom, form a C3-C12 heterocycloalkyl radical; or R1 and R2 form a group â€ƒor R1, R2 and R3 form a group
