Title compound is a useful fluorescense-increasing agent for plastics, synthetic fiber and synthetic rubber. The compound (II) such as o-aminophenol, o- aminothiophenol or o-phenylene diamine and 4-(halomethyl)benzoic acid (III) are reacted with thionylchloride in N-methyl pyrollidone solvent at 120-180 deg.C to give 2-benz-ox-(-ty,-imide)-azolyl-4-halomethyl-benzene (IV), which is reacted with sodium t-butoxide, potasium t-butoxide, KOH or NaOH in polar solvent such as N,N'-dimethyl formamide at -10 - 50 deg.C to give title compound(I).
