Abstract

The present invention provides photolatent Ti-chelate catalyst compounds of formula (I), wherein R1 is for example C6-C14 aryl which is substituted by one or more R′2, R′3 or R′4; or the two R1 together are unsubstituted linear or branched C1-C12alkylene; R2, R3, R4, R′2, R′3, and R′4 independently of each other are for example hydrogen, halogen or linear or branched C1-C20alkyl; R5, R6 and R7 independently of each other are hydrogen, linear or branched C1-C20alkyl, C6-C14aryl, Br or Cl, provided that not more than one of R5, R6 and R7 is hydrogen; as well as formulations comprising said compounds and defined 1,3-diketones.
