Abstract:
An unsymmetrical dioxazine compound represented by the formula (1-1) or (1-2): wherein each of Y1 to Y3 stands for a group represented by the formula (2) or (3) with at least one of Y1 to Y3 being a group represented by the formula (2); X stands for a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an aryl group, an alkoxy group, an acylamino group, or a carboxylate group: wherein h is an integer of 0 to 2, i is an integer of 1 to 2, and j is an integer of 0 to 2; A stands for a group selected from group (I) consisting of: wherein k is an integer of 1 to 6; one or more of hydrogen atoms in a phenylene group may be substituted by an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, a perfluoroalkyl group having 1 to 6 carbon atoms, or a halogen atom; when said A is a group having ends (a) and (b), the end (a) binds to E or G and the end (b) binds to an ester group in the formula (2);each of E, J, and M stands for a group selected from group (I) consisting of: wherein m is an integer of 1 to 12, and each of q and r is an integer of 1 to 8; one or more of hydrogen atoms in a phenylene group may be substituted by an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6carbon atoms, a perfluoroalkyl group having 1 to 6 carbon atoms, or a halogen atom; when E in the formula (2) is a group having ends (a) and (b) , the end (a) binds to G or E and the end (b) binds to A or E; when J in the formula (3) is a group having ends (a) and (b) , the end (a) binds to M, J, or Q, and the end (b) binds to J or the triphenodioxazine skeleton; when M in the formula (3) is a group having ends (a) and (b), the end (a) binds to M or Q and the end (b) binds to M or J;G and Q each stands for a group selected from group (III) consisting of: wherein n is an integer of 1 to 12, and each of q, r, and s is an integer of 1 to 8.
