Title:
OPTICAL RECORDING MATERIAL, OPTICAL RECORDING MEDIUM USING THE OPTICAL RECORDING MATERIAL, AND METHOD FOR REPRODUCING OPTICAL RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2007/136051
Kind Code:
A1
Abstract:
This invention provides an optical recording material, which can solve a problem of
recording density in an optical recording medium, and an optical recording medium
using the optical recording material. The optical recording material comprises
a compound having a structure represented by general formula (I). The optical
recording medium comprises a recording layer containing the optical recording
material. There is also provided a method for reproducing a record in an optical
recording medium wherein recording is carried out by photodissociating a compound
constituting the optical recording material and comprising a luminescent group
and a photodissociating protective group while reproduction is carried out
by reading a difference in luminescence intensity between before the photodissociation and
after the photodissociation. A - (X - B)n (I) wherein A represents a
fluorescence emitting group upon the dissociation of B; X represents a divalent binding
group; B represents a photodissociative protective group; and n is an integer
of 1 to 6.
