Abstract:
Photopolymerizable colorant compounds having Formula I: wherein A is a mono-, di-, tri- or tetravalent anthraquinone chromophore; X is â€”R1â€”O-Q or the photopolymerizable group â€”CH2â€”C6H4-p-C(R2)=CH2; R1 is selected from C2-C8 alkylene, CH2CH2O)m-CH2CH2â€” and 1,4-cyclohexylenedimethylene; R2 is selected from hydrogen and C1-C6 alkyl; n is 1 to 4; m is 1-3; Q is a photopolymerizable group selected from an organic radical having the formula: â€”COC(R3)&boxH;CHâ€”R4â€ƒâ€ƒIa â€”CONHCOC(R3)&boxH;CHâ€”R4â€ƒâ€ƒIIa â€”CONHâ€”C1â€”C6-alkylene OCOC(R3)&boxH;CH-R4â€ƒâ€ƒIIIa wherein R3 is selected from hydrogen or C1-C6 alkyl; R4 is selected from hydrogen; C1-C6alkyl; phenyl; phenyl substituted with one or more groups selected from C1-C6 alkyl, C1-C6 alkoxy, â€”N(C1-C6 alkyl)2, nitro, cyano, C2-C6 alkoxycarbonyl, C1-C6 alkanoyloxy and halogen; 1-and 2-naphthyl; 1- and 2-naphthyl substituted with C1-C6 alkyl or C1-C6 alkoxy; 2- and 3-thienyl; 2- and 3-thienyl substituted with C1-C6 alkyl or halogen; 2- and 3-furyl; and 2- and 3-furyl substituted with C1-C6 alkyl; R5 and R6 are independently selected from hydrogen, C1-C6 alkyl, substituted C1-C6 alkyl; aryl; or R5 and R6 may be combined to represent a â€”(â€”OH2â€”)3.5-radical; R7 is selected from hydrogen or a group selected from C1-C6 alkyl, substituted C1-C6 alkyl, C3-C5 alkenyl, C3-C8 cycloalkyl and aryl; and R8 is selected from hydrogen, C1-C6 alkyl and aryl.
