Abstract:
A triphenodioxazine compound represented by the formula (1): ##STR32##wherein each Y.sup.1 to Y.sup.4 stands for a group represented by the formula (2) or (3) with at least one of Y.sup.1 to Y.sup.4 being a group represented by the formula (2); X stands for a hydrogen atom, a chlorine atom, a bromine atom or a fluorine atom ##STR33##wherein h is an integer of 1, i is an integer of 1 to 2, and j is an integer of 0 to 2, provided that the sum of i and j is not more than 4; A stands for a group selected from group (I) consisting of: ##STR34##wherein k is an integer of 1 to 6; one or two 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; end (a) binds to E and end (b) binds to the ester group in the formula (2);each of E, J, and M stands for a group selected from group (II) consisting of: ##STR35##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 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 6 carbon atoms, 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) selected from group (II), end (a) binds to G or E and end (b) binds to A or E; when J in the formula (3) is a group having ends (a) and (b) selected from group (II), end (a) binds to M, J or Q in the formula (3) and end (b) binds to J or the triphenodioxazine skeleton; when M in the formula (3) is a group having ends (a) and (b) selected from group (II), end (a) binds to M or Q and end (b) binds to M or J; G and Q each stands for a group selected from group (III) consisting of: ##STR36##wherein n is an integer of 1 to 12, and each of q, r, and s is an integer of 1 to 8.
