Metal complexes of halogen-substituted o-benzenedithiols of the general formula: ##STR1## wherein X represents a chlorine or bromine atom, Y and Z represent each a hydrogen or chlorine atom when X is a chlorine atom or they represent each a hydrogen or bromine atom when X is a bromine atom, M represents a nickel, palladium or platinum atom, and A represents a quaternary ammonium group, are provided. These metal complexes have a high compatibility with resins and are useful as near infrared absorbers. Halogen-substituted o-benzenedithiols of the formula: ##STR2## wherein X, Y and Z have the same meaning as above; used as starting materials for the above metal complexes are also new compounds.
卤代对苯二硫醇的金属配合物具有以下一般公式:其中X代表氯或溴原子,Y和Z分别代表氯原子时为氢或氯原子,或者代表溴原子时为氢或溴原子,M代表镍、钯或铂原子,A代表季铵基团。这些金属配合物与树脂具有很高的相容性,可用作近红外吸收剂。具有以下公式的卤代对苯二硫醇:其中X、Y和Z的含义与上述相同;作为上述金属配合物的起始原料也是新化合物。
