    Abstract: A transparent article consists of a transparent substrate coated with a transparent film composed of a composition made up as follows (parts by weight) -100 parts of an organic silicon compound10-30 parts of a polyfunctional epoxy resin having an aromatic or aliphatic ring, and25-800 parts of antimony oxide particles with an average particle size of 1 to 200 nm.The organic silicon compound has the general formula (I)or is a hydrolysis product of a compound within that formula.In formula (1) R' and R 2 each stand for an alkyl group an alkenyl group, an aryl group or a hydrocarbon group having a halogen group, an epoxy group, a glycidoxy group, an amino group, a mercapto group, a methacryloxy group or a cyano group, R 3 stands for an alkyl group having 1 to 8 carbon atoms, an alkoxyalkyl group, an acyl group or a phenyl group, and a and b are 0 or 1.Transparent articles of the invention are suitable for spectacle and camera lenses, and for other optical articles.

    Abstract: PURPOSE:To improve optical characteristics, toughness, and impact strength by copolymerizing a polymerizable prepolymer obtd. by the addition reaction of two specific compsns. with a copolymerizable monomer. CONSTITUTION:50-100 wt.% compd. having two vinyl groups in the molecule and 0-50 wt.% compd. having a vinyl group in the molecule are mixed to give a compsn., which is allowed to undergo the addition reaction with a compsn. comprising at least one dithiol compd. selected from compds. of formula I and II [wherein (a) is 1-6; (b) is 0-2; X is O or S; R is substd. phenylene; (c) is 0 or 1; and (d) is 0-3] in an equivalent ratio between functional groups (CH2=CH)/(SH) of 0.5-1.5, giving a polymerizable prepolymer. The prepolymer is copolymerized with a copolymerizable monomer in the presence of an initiator at 50-140 deg.C for several hr to several tens of hr.

    Abstract: PURPOSE:To improve stain resistance and scratching resistance by providing an antireflecting film, the outermost surface layer film of which consists essentially of silicon dioxide, on the surface of a base material and treating the surface in the environment where a compd. contg. a specific org. silicon substituent exists. CONSTITUTION:The article having at least one layer of the antireflecting film, the outermost surface layer of which consists of the silicon dioxide, is treated in the environment where the org. silicon compd. contg. the substituent expressed by formula I exists. In formula, R , R , R are respectively one kind selected from hydrogen, alkyl group, alkyl halide group, allyl group, aryl group, and aryl halide group; (a), (b) are respectively 0 or 1. X is a hydrolyzable substituent. The article which allows easy removal of stains, has water repellency and is durable against friction is thereby obtd.

    Abstract: PURPOSE:To eliminate the uneven film thickness by the jig traces formed at the time of forming a hard coat film by providing a rim of a specific width to the outside peripheral part of a plastic lens. CONSTITUTION:The rim part 4 having 0.1-5.0mm width is provided to part or the whole of the outer peripheral part of a body 3 of the plastic convex lens 2 consisting of an urethane-modified di(meth)acrylate (co)polymer of a halogenated bisphenol A and the hard coat film is formed on the lens surface. Said coat film is obtd. by gripping the lens 2 by means of; for example, 3-point supporting jigs 1 and subjecting the lens to dip coating and is preferably the film contg. >=10wt% org. silicon compd. expressed by formula and/or cured matter of the hydrolyzate thereof. In formula, R denotes an org. group of 4-20C which has an epoxy group or glycidoxy group and binds to Si at Si-C; (x) denotes a hydrolyzable group; (a) denotes 0, 1.
