  • Publication number: 20130295331
    Abstract: Provided is a transfer film that includes, as a medium-refractive-index film, a film containing metal oxide particles that has a central region in which there are no metal oxide particles, a surface-layer region (a1) formed on one side of the central region and including metal oxide particles, and a surface-layer region (a2) formed on the opposite side of the central region and including metal oxide particles, the transfer film being capable of providing a laminate that has excellent stain resistance, anti-reflection characteristics, transparency, sweat resistance, and scratch resistance, and in which interference patterns are reduced. By using said transfer film, it is possible to obtain a laminate that has excellent stain resistance, anti-reflection characteristics, transparency, sweat resistance, and scratch resistance, and in which interference patterns are reduced.

  • Publication number: 20130258479
    Abstract: Provided is a transfer film wherein: a low-refractive-index film having a refractive index (Nx) and a high-refractive-index film having a refractive index (Ny) are laminated in this order on one surface of a peeling film; the refractive indices satisfy Nx<Ny; and the high-refractive-index film contains an aminosilane. Also provided is a laminate wherein: a high-refractive-index film and a low-refractive-index film are laminated in this order on the surface of a substrate; and the high-refractive-index film contains an aminosilane. The transfer film is obtained by successively laminating and curing a composition for the low-refractive-index film and a composition for the high-refractive-index film on the peeling film. The laminate is produced by bonding the surface of the high-refractive-index film of the transfer film to the substrate, and then peeling away the peeling film.
