  • Publication number: 20250051533
    Abstract: A hard coat film excellent in initial adhesion and light-resistance adhesion between an easy-bonding layer and a hard coat layer on a cycloolefin polymer-based film. The hard coat film includes a hard coat layer containing an ultraviolet curable resin, an ultraviolet absorbing agent, and dye being stacked on at least one surface of a cycloolefin polymer-based film via an easy-bonding layer including ultraviolet curable resin containing inorganic fine particles, and has: a thickness of the easy-bonding layer is 0.1 to 2.0 ?m; a thickness of the hard coat layer 1.0 to 10 ?m; residual rates of the hard coat layer and the easy-bonding layer, measured by a crosscut method of JIS-K5600-5-6, are 100%, and residual rates of the hard coat layer and the easy-bonding layer, after ultraviolet radiation (a light resistance test) for 100 hours in an environment at a temperature of 63° C., at a relative humidity of 50%, and with irradiance of 500 W/m2, are 100%.

  • Patent number: 11859687
    Abstract: A motor and a personal-care device having the motor. The motor has a motor carrier made at least partially from a sheet metal material, a movable motor part, and a spring element that couples the movable motor part with the motor carrier. The sheet metal material comprises at least one coupling area where the sheet metal material is folded so that its two layers are facing each other while each of the two layers comprises a slot, the slots being aligned with one another. A connection extension of the spring element extends through the aligned slots.

  • Publication number: 20170298238
    Abstract: The present invention provides a hard coat film that has an excellent adhesion to the substrate of the hard coat layer and excellent hardness, that has an excellent coating surface without optical unevenness, and that has a high adhesion to acrylic adhesives used to join the hard coat layer and a liquid crystal display member, etc., while having excellent peeling properties from natural rubber-based adhesives. The present invention is a hard coat film comprising a film substrate, and a hard coat layer formed on the film substrate and containing one or more electron beam-curable resins and one or more leveling agents. The above one or more electron beam-curable resins include, for example, a polyfunctional (meth)acrylate resin having 3 or more (meth)acryloyl groups, and the above one or more leveling agents include polyester-modified polydimethylsiloxane.

  • Patent number: 9684098
    Abstract: An antiglare hard coat film formed by providing an antiglare hard coat layer containing fine particles and a resin on a transparent film. When an average value of height in an evaluation region on a surface of the antiglare hard coat film is set at zero (0), a maximum cross sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is from 1.0 to 3.0 ?m, and an average inclination angle of unevenness on the surface of the antiglare hard coat film is 1 degree or less. The total value of the transmissive clarity measured through four optical combs using a transmissive clarity measuring device according to JIS K 7105-1981 is 280% or more, and the value of the transmissive clarity measured through each optical comb is 70% or more, respectively.

  • Patent number: 8758877
    Abstract: An antiglare hard coat film is provided in which light transmittance is high without giving antiglare properties more than necessary, a haze value is low, transparency is excellent, image clarity is high, glare of an image is suppressed, whitishness (white blur) of the film is reduced, contrast deterioration is suppressed, and visibility of the display is improved as compared with prior-art antiglare films. This antiglare hard coat film is formed by providing an antiglare hard coat layer containing organic particulates and a resin on a transparent film. When an average value of height in an evaluation region on the surface of the antiglare hard coat film is set to zero (0), a maximum sectional height represented by a difference between a height maximum value in the evaluation region and a height minimum value in the evaluation region is 0.6 ?m or less.
