Benzene → Naphthalene

wherein m is 0 or 1; --[Ar1 ]-- represents an arylene group (for example, a phenylene group, a naphthylene group, etc.); --[Ph1 ] represents a phenyl group having a water soluble group or a hydrophilic group (as the water soluble group, for example, --SO3M, --COOM, etc., wherein M represents a cation such as an alkali metal ion, an ammonium ion, etc., or a hydrogen atom, and as the hydrophilic group, for example, an amido group, etc.); --[Ar2 ] represents a hydroxynaphthyl group having a water soluble group or a hydrophilic group (as the water soluble group, for example --SO3M, --COOM, etc., wherein M represents a cation such as an alkali metal ion, an ammonium ion, etc., or a hydrogen atom, and as the hydrophilic group, for example, an amido group, etc.), and includes, for example, the following: ##STR8## --[Het] represents an aromatic heterocyclic group, preferably an aromatic heterocyclic group having a water soluble group such as --SO3M or --COOM, wherein M represents a cation such as an alkali metal ion, an ammonium ion, etc., or a hydrogen atom, even more preferably a 5- or 6-membered nitrogen containing aromatic heterocyclic group, and includes, for example, the following: ##STR9## wherein Z represents the non-metallic atomic group necessary to form a fused aromatic ring, e.g., benzene or naphthalene; M represents a cation such as an alkali metal ion, an ammonium ion, etc., or a hydrogen atom; R'1 represents an alkyl group having 1 to 7 carbon atoms, a hydrogen atom, a phenyl group, or a naphthyl group; and R"1 represents an amino group, an alkyl group having 1 to 5 carbon atoms, an acylamino group, most preferably where the acyl moiety contains 1 to 10 carbon atoms, a sulfonamido group, a ureido group, an alkoxycarbonyl group, most preferably where the alkoxy moiety contains from 2 to 10 carbon atoms, a substituted group thereof (which applies to all of the above groups), or a carboxy group; an azomethine dye residue such as those represented by the following formulae: ##STR10## wherein m is 0 or 1; M represents a cation such as an alkali metal cation, an ammonium ion, etc., or a hydrogen atom; and R'2, R'3, R'4 and R'5 each represents an aliphatic hydrocarbon group, for example, an alkyl group having 1 to 5 carbon atoms; a xanthene type dye residue such as those represented by the following formula: ##STR11## wherein m is 0 or 1; an azine type dye residue such as those represented by the following formula: ##STR12## wherein m is 0 or 1; an indoaniline type dye residue such as those represented by the following formulae: ##STR13## wherein R'6, R'7, R'8, R'9, R'10, and R'11 each represents an aliphatic hydrocarbon group, for example, an alkyl group having 1 to 5 carbon atoms;
