  • Patent number: 6998439
    Abstract: The present invention provides a resin composition comprising a vinyl polymer (A) having, at a side chain thereof, at least one structure selected from polyether, polyester, polycarbonate or polybutadiene which has a functional group that can react with an isocyanate group, and a polyisocyanate compound (B) having at least two isocyanate groups; a sheet made of a hardened body of the resin composition; a shaped body formed by shaping the sheet; and a sheet producing process comprising the steps of applying the resin composition and then hardening the resultant layer.

  • Patent number: 5945482
    Abstract: A resin composition for a water-repellent coating which is excellent in adhesion to a substrate and weathering resistance and has a high hardness equivalent to that of a hard coating and excellent acid resistance, which can exhibit these properties in spite of a low fluorine content, the composition containing a polymer (A) formed from 20 to 80% by weight of a fluorine-containing monomer (a) having a carbon-carbon unsaturated double bond and a perfluoroalkyl group, 20 to 80% by weight of a monomer (b) having a carbon-carbon unsaturated double bond and a crosslinkable functional group and 0 to 30% by weight of a monomer (c) having a carbon-carbon unsaturated double bond other than the monomers (a) and (b), and a polymer (B) formed from 20 to 100% by weight of a monomer (b) having a carbon-carbon unsaturated double bond and a crosslinkable functional group and 0 to 80% by weight of a monomer (c) having a carbon-carbon unsaturated double bond other than the monomer (a) and (b), and a water-repellent coating comp

  • Patent number: 5698345
    Abstract: A photosensitive recording material comprising a solvent-soluble, thermosetting epoxy oligomer capable of cationic polymerization, an aliphatic monomer having at least one ethylenically unsaturated bond, the monomer being liquid at normal temperature and pressure, having a boiling point of 100.degree. C. or above at normal pressure and being capable of radical polymerization, a photoinitiator selected from the group consisting of i) a first photoinitiator capable of simultaneously generating a radical species that activates radical polymerization and a Br.o slashed.nsted acid or Lewis acid that activates cationic polymerization, upon exposure to actinic radiation, and ii) a second photoinitiator comprised of a radical polymerization photoinitiator capable of generating a radical species that activates radical polymerization upon exposure to actinic radiation and a cationic polymerization photoinitiator capable of generating a Br.o slashed.
