Abstract
Abstract A curable resin composition comprising a fluoroolefin polymer containing at least 10% by weight of fluorine based on the fluoroolefin unit, being soluble in a solvent and having curable reactive sites, and a curing agent, wherein a polyfluorocarbon chain-containing compound having a functional group reactive with the fluoroolefin polymer and/or the curing agent, is incorporated said composition being useful for the formation of a coating film of excellent water and oil repellency, and stain-proof properties.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
98 words
A curable resin composition comprising (1) a fluoroolefin-alkylvinylether copolymer containing at least 10% by weight of fluorine based on the fluoroolefin unit, and having curable reactive sites, (2) an isocyanate or melamine curing agent, and (3) a C 3 -C 15 perfluorocarbon chain-containing compound which differs from (1) having a function group reactive with the curing agent, wherein the curable reactive sites of the fluoroolefin-alkylvinylether copolymer are hydroxy groups and the C 3 -C 15 perfluorocarbon chain-containing compound which differs from (1) is an alcohol having a C 3 -C 15 perfluoroalkyl group and a hydroxyl functional group.
Claim 2
Dependent Claim
98 words
A curable resin composition comprising (1) a fluoroolefin-alkylvinylether copolymer containing at least 10% by weight of fluorine based on the fluoroolefin unit, and having curable reactive sites, (2) an isocyanate or melamine curing agent, and (3) a C 3 -C 15 perfluorocarbon chain-containing compound which differs from (1) having a function group reactive with the curing agent, wherein the curable reactive sites of the fluoroolefin-alkylvinylether copolymer are hydroxy groups and the C 3 -C 15 perfluorocarbon chain-containing compound which differs from (1) is an alcohol having a C 3 -C 15 perfluoroalkyl group and a hydroxyl functional group.
Claim 3
Dependent Claim
69 words
A curable resin composition comprising (1) a fluoroolefin-alkyl vinyl either copolymer containing at least 10% by weight of fluorine based on the fluoroolefin unit, soluble in a solvent and having curable reactive sites of hydroxy groups, (2) an isocyanate or melamine curing agent, and (3) an alcohol having a C 3 -C 15 perfluoroalkyl group and a hydroxyl functional group reactive with the curing agent which differs from (1).
Claim 4
Dependent Claim
69 words
A curable resin composition comprising (1) a fluoroolefin-alkyl vinyl either copolymer containing at least 10% by weight of fluorine based on the fluoroolefin unit, soluble in a solvent and having curable reactive sites of hydroxy groups, (2) an isocyanate or melamine curing agent, and (3) an alcohol having a C 3 -C 15 perfluoroalkyl group and a hydroxyl functional group reactive with the curing agent which differs from (1).
Claim 5
Dependent Claim
45 words
