Abstract:
1. A photoinitiator compound comprising both a photoactive moiety and a tertiary amino group, bonded to a polyhedral oligomeric silsesquioxane, which 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, except zero; a is an even-numbered integer or uneven-numbered integer, except zero; different A independently of each other are linear or branched C  glycidyl-O-L-, CH  phenyl, halogen-L-, NC-L-, HS-L-, phenyl-L-, C  C(R′ or different A independently of each other are a group of formula (2)  wherein the asterisk * denotes the bond to the silicon; E is a direct bond, linear or branched C or E is linear or branched C or E is  wherein the asterisk * denotes the bond to L and the double asterix ** denotes the bond to the N-atom, or E is linear or branched C L is linear or branched C or L, if E is a direct bond or linear or branched C or L, if E is a direct bond, additionally is phenylene; R or R or R or R  (CO)R or R  wherein the asterisk * denotes the bond to E; R or R or R or R  (CO)R R R R Q is a group of formula (3), (4), (5), (6), (6a) or (7)  in which formulae (3), (4), (5), (6), (6a) and (7) the asterisk * denotes the bonding to the nitrogen in formula (2); Q1 is a group of formula (8), (9), (10), (11), (11a) or (12)  in which formulae (8), (9) (10), (11), (11a) and (12) the asterisk * denotes the bonding to the silicon atom; p is an integer 0, 1, 2, 3 or 4; Z or independently of each other are C or independently of each other are **OC or independently of each other are **OC or independently of each other are **SC or independently of each other are **SC or are **O—C in which definitions the double asterisk ** denotes the bonding to the phenyl ring; Z or is linear or branched O—C Z **—O—C in which definitions the double asterisk ** denotes the bonding to the phenyl ring; Z E1 is  in which definitions the asterisk * denotes the bonding to L; E2 is  in which definitions the asterisk * denotes the bonding to L; X is OR R R R R or R  wherein the asterisk * represents the bond to the C-atom of the carbonyl group of (CO)R R R or R  wherein the asterisk * denotes the bond to E, or R′  wherein the asterisk * denotes the bond to the C-atom of the carbonyl group in (CO)R R R R R R R (CO)R  Si(CH (CO)R R R or R  wherein the asterisk * represents the bond to the C-atom of the carbonyl group of (CO)R R provided that at least one Q and at least one amine functionality via a group of the formula (2) are present in the photoinitiator compound.
