The optical information recording medium comprises a recording layer on a surface of a support. The surface of the support has pregrooves with a track pitch ranging from 50 to 500 nm, and the recording layer comprises a phthalocyanine derivative denoted by general formula (I) and a compound denoted by general formula (II). In general formula (I), R.sup.1 denotes a substituent, n denotes an integer ranging from 1 to 16, and M denotes a metal atom optionally comprising a ligand, a metal oxide, or two hydrogen atoms. In general formula (II), R.sup.2 denotes a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms or a substituted or unsubstituted aryl group having 4 to 24 carbon atoms, and m is an integer ranging from 1 to 4.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
