<P>PROBLEM TO BE SOLVED: To provide a two-photon absorption photosensitive composition which excites two-photon absorption with a relatively low output laser, and utilizes energy in a highly excited state produced as the result of two-photon absorption for initiation energy of a chemical reaction such as polymerization, and also to provide a two-photon absorption optical recording medium using the same. <P>SOLUTION: The photosensitive composition contains a binder polymer, a polymerizable compound and a compound represented by a general formula (I): D-L-A, wherein D represents a light absorption moiety comprising a two-photon absorption compound residue the two-photon absorption cross-sectional area of which at a wavelength longer than 400 nm is ≥100 GM; A represents an active moiety which interacts with the photoexcited light absorption moiety D and generates a free radical; and L represents a linking group which links the light absorption moiety D and the active moiety A together. <P>COPYRIGHT: (C)2008,JPO&INPIT |
