FILM OBTAINED BY LAMINATING COATING LAYER MADE OF FLUORINE-CONTAINING ACRYLIC RESIN ON BASE FILM

摘要

A film includes: a coating layer made of a fluorine-containing acrylic resin; and a base film, on which the coating layer is laminated. The fluorine-containing acrylic resin is obtained by copolymerizing 50 to 99 parts by weight of a monomer represented by a general formula (1) with 50 to 1 parts by weight of a methacrylate-based monomer, and a melt viscosity of the fluorine-containing acrylic resin is less than 300 Pa·s under conditions of a die temperature of 220° C., a shear rate of 122 sec−1, and a capillary die diameter of 1 mm based on JIS K7199.;;In the general formula (1), R1 is a direct bond or a straight-chain or branched-chain alkylene group containing 1 to 4 carbon atoms, and R2 is methyl.

1. A film comprising:
a coating layer made of a fluorine-containing acrylic resin; and a base film, on which the coating layer is laminated, wherein the fluorine-containing acrylic resin is obtained by copolymerizing 50 to 99 parts by weight of a monomer represented by a general formula (1) with 50 to 1 parts by weight of a methacrylate-based monomer, wherein a melt viscosity of the fluorine-containing acrylic resin is less than 300 Pa*s under conditions of a die temperature of 220° C., a shear rate of 122 sec−1, and a capillary die diameter of 1 mm based on JIS K7199, and wherein a water contact angle of the coating layer at a temperature of 80° C. is not less than 85° C., wherein in the general formula (1), R1 is a direct bond or a straight-chain or branched-chain alkylene group containing 1 to 4 carbon atoms, and R2 is methyl.
