Title:
OPTICAL RECORDING MEDIUM AND VISIBLE INFORMATION RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/122830
Kind Code:
A1
Abstract:
An optical recording medium comprising a substrate and a visible information
recording layer provided on the substrate, the visible information recording
layer containing a coloring matter represented by general formula (I). In general
formula (I), A represents a substituted or unsubstituted heterocyclic group,
a substituted aliphatic group, or a substituted or unsubstituted carbocyclic
group, and B represents a substituted or unsubstituted heterocyclic group,
or a substituted or unsubstituted aryl group. The optical recording medium
may further comprise a recording layer capable of recording and/or reproducing
information by the application of a laser beam thereto. The present invention
also provides a method for recording visible information in the visible information
recording layer of the optical recording medium, wherein the visible information
is recorded using the same laser beam as employed for recording information in
the above recording layer.
