PURPOSE:To realize a more efficient water-soluble PHB optical recording medium by making a substituent of zinc tetratryltetrabenzoforfine to be a water-soluble group that a water-soluble acceptor (electron acceptor) such as cinnamic bromide can be used. CONSTITUTION:This PHB optical recording medium has a recording layer consisting of a medium, photosensitive molecules dispersed in the medium, and acceptor dispersed or bonded with the medium. The photosensitive molecule is a zinc tetrabenzoforfin deriv. having a water-soluble phenyl group (e.g. phenyl group having suger as substituent). |
