CA 2483004

Compounds of formula (I), wherein Y is, for example, C3-C,12alkylene, butenylene, butynylene, or C4-C,12alkylene interrupted one or more times by non-consecutive -O- or -NR2-; R1 is a reactive group selected from OH, SH, NR3R4, -(CO)-OH, -(CO)-NH2, SO3H, -C(R5)=CR6R7, oxiranyl, -O-(CO)-NH-R8-NCO and -O-(CO)-R9-(CO)-X; R2 is hydrogen, C1-C4alkyl or C2-C4 hydroxyalkyl; R3 and R4 are each independently of the other hydrogen, C1-C4alkyl or C2- C4hydroxyalkyl ; R5, R6 and R7 are each independently of the others hydrogen or methyl; R8 is, for example, linear or branched C4-C12alkylene, or phenylene; R9 is, for example, linear or branched C1-C16alkylene, -CH=CH-, - CH=CH-CH2-, C6-cyclo~alkylene, phenylene or naphthylene; and X, X1 and X2 are each independently of the others OH, Cl, OCH3 or OC2H5; are suitable as photoinitiators that can be incorporated in a formulation to be cured.

L'invention concerne des composés de formule générale (I), dans laquelle Y est, par exemple, C¿3?-C,¿12?alkylène, buténylène, butynylène, ou C¿4?-C¿12?alkylène interrompu une ou plusieurs fois par -O- ou -NR¿2?- non consécutif; R¿1? est un groupe réactif sélectionné parmi OH, SH, NR¿3?R¿4?, -(CO)-OH, -(CO)-NH¿2?, SO¿3?H, -C(R¿5?)=CR¿6?R¿7?, oxyranyle, -O-(CO)-NH-R¿8?-NCO et -O-(CO)-R¿9?-(CO)-X; R¿2? est hydrogène, C¿1?-C¿4?alkyle ou C¿2?-C¿4? hydroxyalkyle; R¿3? et R¿4? sont indépendamment l'un de l'autre hydrogène, C¿1?-C¿4?alkyle ou C¿2?-C¿4?hydroxyalkyle; R¿5?, R¿6? et R¿7? sont indépendamment les uns des autres hydrogène ou méthyle; R¿8? est, par exemple, C¿4?-C¿12?alkylène linéaire ou ramifié, ou phénylène; R¿9? est, par exemple, C¿1?-C¿16?alkylène linéaire ou ramifié, -CH=CH-, -CH=CH-CH¿2?-, C¿6?-cyclo-alkylène, phénylène ou naphthylène; et X, X¿1? et X¿2? sont indépendamment les uns des autres OH, Cl, OCH¿3? ou OC¿2?H¿5?; qui sont aptes à être utilisés en tant que photo-initiateurs pouvant être incorporés à une formulation à durcir.
