A composition for an ultraviolet absorbent substance which comprises at least one metal complex represented by formula and at least one matrix material and/or polymerizable monomer as a precursor of a matrix material and wherein the matrix material comprises an organic or inorganic binder, which is at least one of poly(meth)acrylate resins, polystyrene resins, styrene copolymers, polyester resins, polyolefin resins, polyether resins, silicone resins, polycarbonate resins, epoxy resins, phenol resins and polyvinyl resins, or a polysiloxane binder: Wherein Y 1, Y 2, Y 3 and Y 4 are each, independently of one another, NH, NR 5, an oxygen atom or a sulfur atom, and R 5 of NR 5 assigned to Y 1, Y 2, Y 3 or Y 4 is an alkyl group having 1 to 8 carbon atoms or an aryl group having 6 to 15 carbon atoms, which may have substituent(s), provided that when at least two of Y 1, Y 2, Y 3 and Y 4 are represented by NR 5, these occurrences of R 5 of NR 5 each represent a substituent which is independent of one another; Z 1 and Z 2 are each a nitrogen atom; and each of R 1, R 2, R 3 and R 4 is absent or, if present, one to four of 4 hydrogen atoms bound to 4 carbon atoms other than 2 carbon atoms shared with a five-membered ring among 6 carbon atoms of one benzene ring can be substituted, and all of substituents substituting for hydrogen atom(s) of the four benzene rings are each, independently of one another, an alkyl group having 1 to 8 carbon atoms, which may have substituent(s), a hydroxyl group, a carboxyl group, an alkoxy group having 1 to 4 carbon atoms, a halogeno group, an alkylaminosulfonyl group having 1 to 8 carbon atoms, which may have substituent(s), a morpholinosulfonyl group which may have substituent(s), a piperidinosulfonyl group which may have substituent(s), a pyrrolidinosulfonyl group which may have substituent(s), a thiomorpholinosulfonyl group which may have substituent(s) or a piperazinosulfonyl group which may have substituent(s), and M represents a metal atom. Y 1, Y 2, Y 3 and Y 4 are each, independently of one another, NH, NR 5, an oxygen atom or a sulfur atom, and R 5 of NR 5 assigned to Y 1, Y 2, Y 3 or Y 4 is an alkyl group having 1 to 8 carbon atoms or an aryl group having 6 to 15 carbon atoms, which may have substituent(s), provided that when at least two of Y 1, Y 2, Y 3 and Y 4 are represented by NR 5, these occurrences of R 5 of NR 5 each represent a substituent which is independent of one another; Z 1 and Z 2 are each a nitrogen atom; and each of R 1, R 2, R 3 and R 4 is absent or, if present, one to four of 4 hydrogen atoms bound to 4 carbon atoms other than 2 carbon atoms shared with a five-membered ring among 6 carbon atoms of one benzene ring can be substituted, and all of substituents substituting for hydrogen atom(s) of the four benzene rings are each, independently of one another, an alkyl group having 1 to 8 carbon atoms, which may have substituent(s), a hydroxyl group, a carboxyl group, an alkoxy group having 1 to 4 carbon atoms, a halogeno group, an alkylaminosulfonyl group having 1 to 8 carbon atoms, which may have substituent(s), a morpholinosulfonyl group which may have substituent(s), a piperidinosulfonyl group which may have substituent(s), a pyrrolidinosulfonyl group which may have substituent(s), a thiomorpholinosulfonyl group which may have substituent(s) or a piperazinosulfonyl group which may have substituent(s), and M represents a metal atom.
