  • Patent number: 11065851
    Abstract: One embodiment provides a multilayer hard coating film which sequentially includes, from the superficial layer side, a first hard coating and a resin film, and wherein: the first hard coating is formed from a coating material that contains a specific amount of (A) a polyfunctional (meth)acrylate and a specific amount of (B) a water repellent agent, while containing no inorganic particles; and the resin film includes at least one layer of (?) an acrylic resin that contains 50-95% by mole of a structural unit derived from methyl methacrylate and 50-5% by mole of a structural unit derived from vinyl cyclohexane when the total of the structural units derived from polymerizable monomers is taken as 100% by mole.

  • Publication number: 20210122146
    Abstract: Embodiments provide a multilayer film in which: a first acrylic resin layer (?1), an aromatic polycarbonate resin layer (?), and a second acrylic resin layer (?2) are directly laminated in the stated order; the aromatic polycarbonate resin constituting the aromatic polycarbonate resin layer (?) is a product of ester exchange between a polycarbonic acid ester of an aromatic dihydroxy compound and a low-crystalline or amorphous aromatic polyester; and the relationships (T??T?1)?30 and (T??T?2)?30 (where Tal is the glass transition temperature of the acrylic resin constituting the first acrylic resin layer (?1), T?2 is the glass transition temperature of the acrylic resin constituting the second acrylic resin layer (?2), T? is the glass transition temperature of the aromatic polycarbonate resin constituting the aromatic polycarbonate resin layer (?), and all of the temperatures are measured in degrees Celsius) are satisfied.

  • Publication number: 20200223205
    Abstract: Embodiments provide a method for producing a multilayer film, the method including: (A) a step for continuously coextruding from a T die (3) a molten film (4) of a multilayer film in which a first acrylic resin layer (?1), an aromatic polycarbonate resin layer (?), and a second acrylic resin layer (?2) are directly laminated in the stated order using a coextrusion apparatus; (B) a step for feeding and pressing the molten film of the multilayer film between a first mirror surface body (5) that rotates or revolves and a second mirror surface body (6) that rotates or revolves so that the first acrylic resin layer (?1) is disposed on the first-mirror-surface-body side; and (C) a step for holding the pressed multilayer film against the first mirror surface body and sends the pressed multilayer film to the subsequent third mirror surface body (8) that rotates or revolves, where TR1 (surface temperature of first mirror surface body), TR2 (surface temperature of second mirror surface body), T?1 (glass transition temp

  • Publication number: 20180009959
    Abstract: According to at least one embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (?) a hard coat on at least one surface of (?) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4?-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %. According to another embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (?) a hard coat on at least one surface of a transparent laminate film constituted of (?) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4?-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol, when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %, and (?) a poly(meth)acrylimide resin film.
