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 composition which is a solution of the above resin composition in a solvent.

Resin composition for water-repellent coating and water-repellent coating

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.nsted acid or Lewis acid that activates cationic polymerization upon exposure to actinic radiation, and a spectral sensitizer that sensitizes the first photoinitiator or second photoinitiator; the aliphatic monomer being mixed in an amount of from 20 parts by weight to 80 parts by weight based on 100 parts by weight of the thermosetting epoxy oligomer. Use of this photosensitive recording material is effective for producing a volume type phase hologram having superior diffraction efficiency, transparency and weatherability such as thermal resistance and being chemically stable.
