  • Pyran derivative, photosensitive resin composition, and hologram recording medium using it
    Patent number: 5492942
    Abstract: A pyran derivative has a structure ofR.sup.2 R.sup.3 C.dbd.(C.sub.5 H.sub.2 R.sup.1 O)--(CH.dbd.CH).sub.n --C.sub.6 H.sub.2 R.sup.6 R.sup.7 --NR.sup.4 R.sup.5wherein n is 3 or 4; R.sup.1 is a proton, alkyl or phenyl group; each of R.sup.2 and R.sup.3 is independently a cyano, alkoxycarbonyl having an alkyl, acyl having an alkyl, aracyl having phenyl, sulfonyl, aryl, or aryloxy; each of R.sup.4 and R.sup.5 is an alkyl group; and each of R.sup.6 and R.sup.7 is a proton, provided that R.sup.4 and R.sup.5 are alkyl groups, and a pair of R.sup.4 and R.sup.6 as well as a pair of R.sup.5 and R.sup.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 pyran derivative. A photosensitive resin composition comprises a crosslinkable polymer, a crosslinking agent and the photosensitizer.

  • Photo-crosslinkable resin composition and hologram recording medium
    Patent number: 5422204
    Abstract: A photo-crosslinkable resin composition comprises (a) a polymer having an electron-donating group in a monomer unit, (b) a halogen compound, (c) an onium salt and (d) at least one sensitizer selected from the group consisting of coumarin derivatives, rhodanine derivatives, thioxanthene derivatives and unsaturated cyclopentanone compounds. The composition can be used as a hologram recording medium.
