摘要:
The present invention provides an optical film including: a base; a first functional layer provided on one principal plane of the base via a first adhesion-improving layer; and a second functional layer that is different from the first functional layer and is provided on the other principal plane of the base via a second adhesion-improving layer. The first adhesion-improving layer contains a resin that is different from a resin contained in the second adhesion-improving layer, and the second functional layer contains a resin of the same type as the resin contained in the second adhesion-improving layer. The optical film according to the present invention achieves excellent adhesion between the respective functional layers and the base as well as excellent reflectance spectral characteristics.

An antireflection film including a polyester base 10 and an antireflection layer that is disposed on a side 10a of one principal surface of the polyester base 10 by the wet coating method. The antireflection layer includes, from a side of the polyester base 10, a hard coat layer 11 and a low-refractive index layer 12 that is disposed above the hard coat layer. The hard coat layer is provided directly on the polyester base 10, the hard coat layer contains a metal oxide, and the metal oxide is contained in a ratio of 20 vol % to 42 vol %. The present invention provides an antireflection film in which a primer layer for improving adhesion is not provided between a polyester base and a hard coat layer and the occurrence of interference fringes is suppressed, and that delivers excellent antireflection performance and exhibits high scratch resistance, and a display front plate using the antireflection film.

An optical film according to the present invention comprises a transparent base, and an anti-reflection layer that is disposed on one main face of the transparent base. The anti-reflection layer includes a hard coating layer, and a low refractive index layer that is disposed on the hard coating layer in this order from the side of the transparent base. The hard coating layer is formed using a resin containing an ionizing radiation setting resin. The hard coating layer contains a conductive metal oxide in an amount of at least 5 wt % and at most 30 wt % with respect to the total weight of the hard coating layer. The hard coating layer is formed using a coating solution containing water in an amount of at least 0.05 wt % and at most 5.0 wt %.

摘要:
To increase the heat resistance of a film capacitor, a cured article obtained by curing a mixed solution of a polyvinyl acetal having a hydroxyl group content of 10% to 38% by weight, the number of backbone carbon atoms of the polyvinyl acetal being 100 or more, and a polyisocyanate having an isocyanate content of 1% to 50% by weight is used as a dielectric resin films material arranged between first and second counter electrodes facing each other. At least the polyvinyl acetal is subjected to high-pressure homogenization in which a shearing force is applied such that a pressure applied to the polyvinyl acetal is 50 MPa or more when the material is passed through a path having a diameter of 0.125 mm and a length of 5 mm, so that the solubility is increased to allow a curing reaction to proceed uniformly. The cured article has a glass transition temperature of 130° C. or higher and a breakdown voltage of 350 V/μm or more.
