Abstract:
To provide a fluorinated ether compound capable of imparting excellent antifouling properties (oil-based ink repellency, fingerprint stain removability) to a hard coating layer, etc., a composition for forming a hard coating layer, containing such a compound, and an article having an antifouling hard coating layer formed from such a composition.A fluorinated ether compound which has either a poly(oxyperfluoroalkylene) chain having a unit repeated that comprises a group constituted by one to three of at least one type of a C1-2 oxyperfluoroalkylene group and a group constituted by one to three of at least one type of a C3-6 oxyperfluoroalkylene group, bonded to each other, or a poly(oxyperfluoroalkylene) chain having a unit repeated that comprises a C4 oxyperfluoroalkylene group and an oxyperfluoroalkylene group other than such a group, bonded to each other, a linking group bonded to a first terminal of the above poly(oxyperfluoroalkylene) chain, and at least one (meth)acryloyl group bonded to the above linking group; a composition for forming a hard coating layer containing such a compound; and an article having such a hard coating layer.
Abstract:
Provided is a fluorinated ether compound capable of imparting excellent antifouling properties such as oil-based ink repellency, fingerprint stain removability, to a hard coating layer; a composition for forming a hard coating layer, and an article having an antifouling hard coating layer formed from the composition. The fluorinated ether compound has either a poly(oxyperfluoroalkylene) chain having a repeated unit that includes a C1-2 oxyperfluoroalkylene group and a C3-6 oxyperfluoroalkylene group, bonded to each other, or a poly(oxyperfluoroalkylene) chain having a repeated unit that contains a C4 oxyperfluoroalkylene group and a different oxyperfluoroalkylene group, bonded to each other, a linking group bonded to a first terminal of the poly(oxyperfluoroalkylene) chain, and at least one (meth)acryloyl group bonded to the linking group.
Abstract:
To provide a process for producing a charge retention medium, with which a coating film (precursor of a charge retention medium) containing a fluorinated copolymer having repeating units based on tetrafluoroethylene and repeating units based on ethylene can easily be formed on the surface of a substrate, even in a case where the surface of the substrate has a complicated shape.A process for producing a charge retention medium (electret 30), which comprises a step of applying a coating composition containing a fluorinated copolymer (A) having repeating units based on tetrafluoroethylene and repeating units based on ethylene, and an organic solvent (C), to a substrate (first substrate 10) to form a coating film.
