摘要:
A naphthalocyanine derivative having as substituents at least one group of a formula: SR.sup.1 wherein R.sup.1 is --(CR.sup.2 R.sup.3).sub.x SiR.sup.4 R.sup.5 R.sup.6, in which R.sup.2 to R.sup.6 are H, alkyl groups, etc. is excellent in solubility in saturated hydrocarbon solvents and in absorption of semiconductor laser lights and thus, is suitable for producing optical recording media.
