摘要:
An anti-fogging coating solution comprising a homopolymer of a repeating unit derived from an ethylenic monomer having a hydroxyl group in the side chain or a copolymer of the above repeating unit and a repeating unit derived from an ethylenic monomer having an epoxy group, alkoxycarbonyl group, carboxyl group, amido group or amino group in the side chain as a resin component. A film formed from the coating solution of the present invention has excellent scratch resistance, initial anti-fogging property and anti-fogging retainability.

A plastic lens formed by laminating, in the order as described below,(A) a plastic lens substrate having a refractive index in the range of 1.50 to 1.70,(B) a primer layer containing a metal compound of at least one metal selected from the group consisting of Al, Ti, Zr, Sn and Sb and a polyurethane, or(B') a primer layer formed from a polyurethane containing at least one element selected from the group consisting of Cl, Br, I and S,(C) a hard coating layer, and(D) a single-layered or multi-layered anti-reflection layer formed by vapor-depositing an inorganic substance.
摘要:
A light control sheet capable of scattering an incident light of particular incident angle is produced by a method composed of preparing a film of a composition containing at least two photopolymerizable components having different refractive indexes, irradiating on the film a light from a particular direction, and obtaining a cured film of the light control sheet product. Such other light control sheets as capable of scattering a plurality of incident lights each of particular incident angle are obtained by modification of the above-mentioned method.
摘要:
A coating composition comprising (1) an anionic surfactant comprising a sulfonic acid salt, (2) a sol of fine inorganic oxide particles, (3) a silicon compound having one acryl or methacryl group and a hydrolyzable group or a product of hydrolysis of the compound, (4) a compound having at least two photopolymerizable unsaturated groups, and (5) a photopolymerization initiator; and a coated article obtained by applying the coating composition to a base and then photocuring the coating. The coated article combines antifogging properties with abrasion resistance sufficient for practical use.
摘要:
A coating composition capable of yielding a cured product having a high refractive index comprises fine particles of at least one oxide selected from the group consisting of iron oxide, titanium oxide, cerium oxide, zirconium oxide, antimony oxide, zinc oxide and tin oxide, and composite oxides thereof, an epoxy group-containing silicon compound or a partial hydrolyzate thereof, and an organic compound having one OH group or SH group in the molecule and containing in the main chain thereof at least one bonding unit selected from the group consisting of --O--, --CO--O--, --S--, --CO--S-- and --CS--S-- along with at least one unsaturated group, the organic compound being soluble in water or a lower alcohol having up to 4 carbon atoms. When cured on a high refractive index substrate, the composition yields a cured product which has a very high hardness and is able to be deep dyed while suppressing development of interference fringes. Coated articles including coated plastic lenses having the cured film of the composition are also provided.
摘要:
A composition for an optical material, which comprises an N-phenylmaleimide, a di(meth)allyl diphenate and a bisphenol ester.The N-phenylmaleimide, the di(meth)allyl diphenate and the bisphenol ester are contained in amounts of 1 to 50% by weight, 5 to 50% by weight and 1 to 30% by weight, based on the total weight of these components, respectively, The composition affords a three-dimensionally crosslinked resin by radical polymerization. The resin is useful for an optical material.
摘要:
The present invention relates to an automobile window material that can be prevented from suffering from fogging even when exposed to outside air having a considerably low temperature, as well as an automobile having such a window material. The automobile window material is configured to be affixed to an opening of an automobile, and includes a substrate and a coating film provided on that surface of the substrate which faces to an interior of the automobile when affixed to the opening of the automobile. The coating film contains a surfactant capable of adsorbing and holding water vapor and a hydrophilic organic material.
摘要:
A coating composition comprising (A) 0.05 to 7% by mass of a fluoro group-containing silicon compound or a hydrolysate thereof, (B) 5 to 65% by mass of fine particles of the oxide of at least one metal selected from the group consisting of Si, Al, Sn, Sb, Ta, Ce, La, Fe, Zn, W, Zr, In and Ti, (C) 10 to 80% by mass of a specific silicon compound or a partial hydrolysate thereof, and (D) 0.1 to 60% by mass of a compound which can react with an epoxy group or a silanol group, wherein the amount of the component (A) is based on the mass of the component (C), and the amounts of the components (B), (C) and (D) are based on the total mass of the components (A), (B), (C) and (D). This composition provides to a plastic lens a hard coat layer which is free from a dyeing speck even when it is dyed after it is stored for a long period of time, experiences a small change in the color of a dye before and after storage, can be dyeable and has high hardness.
