Abstract: There is provided a pre-antifogging article for obtaining an antifogging article that shows hydrophilicity, the pre-antifogging article being characterized in that it has a base member and a film that is formed on the base member and comprises a urethane resin having an oxyethylene chain having a water absorption percentage of 10-40 wt %, and that a nonionic surfactant having an oxyethylene chain is supported in the film comprising the urethane resin.

Abstract: The present invention relates to a glass substrate which is characterized in that it has a primer layer that is formed thereon and includes a hydrolysis product of a hydrolysable silicon compound having an alkylene group and a hydrolysis product of a hydrolysable zirconium compound or hydrolysable titanium compound, and that, in the primer layer, zirconium is in an amount by weight ratio of 0.0002 times to 0.0025 times that of silicon, or titanium is in an amount by weight ratio of 0.0005 times to 0.0045 times that of silicon. Furthermore, the present invention relates to an anti-fogging article having a resin film that exhibits water-absorptive property and/or hydrophilic property and is formed on the primer layer of the glass substrate.

Abstract: The invention relates to a method for putting color to glass by irradiating a silicate glass, containing a non-bridging oxygen in its structure, with a laser light, thereby forming a non-bridging oxygen hole center therein to put a color to the glass. The invention further relates to a method for putting color to glass by irradiating a silver-ion-containing glass with a high-energy light, thereby forming silver particles in the glass through aggregation of silver ions to put a color to the glass. The invention further relates to a method for erasing color from colored glass by irradiating a colored portion of a glass with a laser light to selectively heat the colored portion by using a laser irradiation apparatus comprising (a) a laser oscillator, (b) a light modulator, (c) a condenser lens mounted on a linear translator, (d) an objective lens, and (e) a galvanometer mirror.

Abstract: A first coating solution for forming a colored film on a glass substrate contains a titanium alkoxide; a silicon alkoxide; a coloring agent that is a nitrogen-containing organic compound; and an organic solvent dissolving the titanium alkoxide, the silicon alkoxide and the nitrogen-containing organic compound. A second coating solution therefor contains a titanium alkoxide; a silicon alkoxide; and an organic solvent dissolving the titanium alkoxide and the silicon alkoxide. At least one of these titanium alkoxide and silicon alkoxide of the second coating solution contains in the molecule a nitrogen-containing organic group derived from a nitrogen-containing organic compound.
