Patent ID: 8906979

Claim:
A photoinitiator compound comprising a photoactive moiety Q and an amine functionality, the photoinitiator compound represented by formula (1) wherein R 4 and R 5 are a photoactive moiety Q; R 6 is linear or branched C 1 -C 20 alkyl which optionally is substituted by one or more identical or different Y 2 ; or is linear or branched C 2 -C 20 alkyl which is interrupted by one or more identical or different Y 1 and which interrupted C 2 -C 20 alkyl optionally is substituted by one or more identical or different Y 2 ; or is a group E-R 9 or E 1 -R 13 ; Q is a photoactive moiety wherein the asterisk (*) denotes the bonding to the N atom; g and g′ are 0; R 1 and R′ 1 independently of each other are hydrogen, linear or branched C 1 -C 6 alkyl, OC 1 -C 3 alkyl, OR 3 , NO 2 , CN, (CO)OR 2 or halogen; Z is a group wherein the double asterisk (**) denotes the bonding to the phenyl ring and the asterisk (*)denotes the bonding to the nitrogen atom; X is O; R 2 is hydrogen or C 1 -C 6 alkyl; R 3 is hydrogen or (CO)CH 3 ; Y 1 is O or NR 16 ; Y 2 is N(R 10 )(R 11 ); R 9 is G 2 -N(R 10 )(R 11 ) or hydrogen; R 10 and R 11 independently of each other are a photoactive moiety Q, hydrogen, or R 10 and R 11 are linear or branched C 2 -C 18 alkyl which is interrupted by one or more O and which interrupted C 2 -C 18 alkyl optionally is substituted by OR 12 ; R 12 is hydrogen; R 13 is N(R 10 )(R 11 ); R 16 is a photoactive moiety Q, hydrogen, or linear or branched C 2 -C 18 alkyl which is interrupted by one or more O and which interrupted C 2 -C 18 alkyl optionally is substituted by OR 12 or NR 10 R 11 ; E is a group wherein the asterisk (*) denotes the bond to the N-atom; G 2 in the multiple occurring moieties are identical or different and are linear or branched C 2 -C 6 alkylene; a in the multiple occurring moieties independently are an integer 1-50; M in the multiple occurring moieties are identical or different and are O or N(R 16 ); E 1 is a group wherein the asterisk (*) denotes the bond to the N-atom; e is 1; G 3 in the multiple occurring moieties are identical or different and are linear or branched C 2 -C 6 alkylene; the sum of b+c+d is an integer 1-12; and R 23 is linear or branched C 1 -C 6 alkyl.
