  • Patent number: 11072673
    Abstract: A methacrylic resin excellent in moldability, solvent resistance, mechanical properties and heat resistance is provided. A method for producing a methacrylic resin excellent in productivity is provided. A methacrylic resin having 99.1% by mass or more and 99.9% by mass or less of a repeating unit derived from methyl methacrylate, 0.1% by mass or more and 0.9% by mass or less of a repeating unit derived from alkyl acrylate, and a proportion of the molecular weight component of ? or less of the peak molecular weight Mph in the high molecular weight region side obtained from an elution curve by a gel permeation chromatography of the methacrylic resin is 7% or more and 40% or less.

  • Patent number: 10927198
    Abstract: A cured product that is reduced in warping and has high hardness can be obtained from an active energy ray-curable resin composition which uses a methacrylic acid ester polymer that has an acid value of 50 mg KOH/g or less and a transition metal content of 1 ppm or less, while containing 80% by mole or more of a polymer that has a double bond-terminated structure represented by formula (1). (In formula (1), R represents an alkyl group, a cycloalkyl group or an aryl group.

  • Publication number: 20120267042
    Abstract: An object of the present invention is to provide a transfer film in which the function layer such as an anti-reflective layer can be laminated using a film having high surface tension, and a laminate including a soil resistant layer formed by a wet method and having high water repellency and oil repellency and high transparency, scratch resistance, and sweat resistance can be provided, and a method for producing the transfer film. A transfer film according to the present invention is a transfer film including a transparent base material film and a soil resistant cured film laminated on the surface of the transparent base material film, wherein a water contact angle (1) of a surface of the soil resistant cured film not contacting the transparent base material film is not more than 100°, a water contact angle (2) of a surface of the soil resistant cured film contacting the transparent base material film is not less than 90°, and a contact angle (?) of triolein is not less than 55°.

  • Patent number: 5612388
    Abstract: A polyfunctional cationic monomer produced by reacting a tertiary amine having a polymerizable vinyl group with a compound having two or more oxirane groups. The polyfunctional cationic monomer of the present invention shows a very high curing rate and a high reaction suitability as a radiation cure coating to be applied onto the surface of a molded article made of plastics, wood, metals, etc. or the surface of a sheet such as a paper, a film, a metal plate, a knitted web, etc.
