The invention relates to novel photoinitators of formulae (I), (II), (III), (IV), (V) and (VI) wherein R1 and R2 are each independently of the other C1-C8alkyl; C1-C4alkyl substituted by OH, C1-C4alkoxy, -COO(C1-C8alkyl), (C1-C4alkyl)-COO-, -CN, benzyl, phenyl or by -N(R15)(R16); C3-C6alkerlyl, benzyl, -CH2-C6H4-(C1-C4alkyl) or phenyl; or R1 and R2 together are unbrarched or branched C2-C9alkylene or C3-C6-oxa- or -azaalkylene; R3, R4, R5 and R6 are each independently of the others hydrogen, C1-C8alkyl, C3-C6alkenyl, benzyl, -CH2-C6H4-(C1-C4alkyl) or phenyl; R3 and R4 together and/or R5 and R6 together are unbranched or branched C2-C9alkylene; A is CI, Br, -O-R9, -N(R11)(R12) or -S-R18, A' is -O-, -NH- or -NR11-; A' is CI, Br, -O-R9, -N(R11)(R12) or -S-R18 or hydrogen, X is -O-R10 or -N(R13)(R14), n is an integer from 1 to 10, preferably an integer from 1 to 4, especially 1, 2 or 3; R7 is a linker; R8 is a bivalent C2-C3alkylele radical.
该发明涉及以下式(I)、(II)、(III)、(IV)、(V)和(VI)的新型光引发剂,其中R1和R2各自独立地为C1-C8烷基;C1-C4烷基被OH、C1-C4烷氧基、-COO(C1-C8烷基)、(C1-C4烷基)-COO-、-CN、苄基、苯基或-N(R15)(R16)取代;C3-C6烷基、苄基、-CH2-C6H4-(C1-C4烷基)或苯基;或者R1和R2一起为非支链或支链的C2-C9烷基或C3-C6氧或-氮杂环烷基;R3、R4、R5和R6各自独立地为氢、C1-C8烷基、C3-C6烯基、苄基、-CH2-C6H4-(C1-C4烷基)或苯基;R3和R4一起和/或R5和R6一起为非支链或支链的C2-C9烷基;A为CI、Br、-O-R9、-N(R11)(R12)或-S-R18,A'为-O-、-NH-或-NR11-;A'为CI、Br、-O-R9、-N(R11)(R12)或-S-R18或氢,X为-O-R10或-N(R13)(R14),n为1到10的整数,最好为1到4的整数,特别是1、2或3;R7为连接剂;R8为二价的C2-C3烷基基团。
