Abstract:
A pyran derivative has a structure of R<2>R<3>C=(C5H2R<1>O)-(CH=CH)n-C6H2R<6>R<7>-NR<4>R<5> wherein n is 3 or 4; R<1> is a proton, alkyl or phenyl group; each of R<2> and R<3> is independently a cyano, alkoxycarbonyl having an alkyl, acyl having an alkyl, aracyl having phenyl, sulfonyl, aryl, or aryloxy; each of R<4> and R<5> is an alkyl group; and each of R<6> and R<7> is a proton, provided that R<4> and R<5> are alkyl groups, and a pair of R<4> and R<6> as well as a pair of R<5> and R<7> can be bonded to each other to form a heterocycle. A photosensitive composition comprises a polymerizable compound, a polymerization initiator and a photosensitizer which is the phyran derivative. A photosensitive resin composition comprises a crosslinkable polymer, a crosslinking agent and the photosensitizer. A hologram recording medium mainly comprises the photosensitive composition or the photosensitive resin composition.
