    摘要: The invention provides a liquid coating composition for forming a transparent and hard coating film on a plastic member such as a polycarbonate or polymethyl methacrylate plate. The liquid composition comprises 100 parts by weight of an organotrialkoxysilane R.sup.1 Si(OR.sup.2).sub.3, where R.sup.1 is a C.sub.1 - or C.sub.2 -alkyl group and R.sup.2 is a C.sub.1 -, C.sub.2 - or C.sub.3 -alkyl group, 5-20 parts by weight of an organotrialkoxysilane R.sup.3 Si(OR.sup.2).sub.3, where R.sup.3 is an organic group containing epoxy group, 50-200 parts by weight of an aqueous colloidal silica sol in which the content of SiO.sub.2 is 10-40 wt %, and 0.5-3 parts by weight of a dicarboxylic acid (CF.sub.2).sub.n (COOH).sub.2, where n is an integer from 1 to 5, preferably hexafluoroglutaric acid. On a surface of a plastic member a coating film of this composition is partially cured at 70.degree.-150.degree. C. to turn into a fairly hard but still pliable film. Then the plastic member can be shaped so as to bend the coated surface without suffering from cracking or peeling of the partially cured film. After that the film is treated with an aqueous alkali solution and then further cured at 80.degree.-150.degree. C.

    摘要: An ultraviolet and infrared absorbing glass plate includes a transparent glass substrate, a first layer formed on a first major surface of the glass substrate and a second layer formed on the first layer. The first layer is an ultraviolet and infrared absorbing film prepared by hardening a primer coating solution. The primer coating solution contains a synthetic resin, a fluorescent brightening agent, an ultraviolet absorbing agent and an infrared absorbing agent. The second layer is a film of a siloxane polymer. The glass plate has an optional water-repellent layer formed on a second major surface of the glass substrate. Long-wavelength ultraviolet rays until the upper limit of its wavelength can be substantially cut by the first layer on the glass substrate. Furthermore, the first layer is superior in infrared absorption, adhesion to the glass substrate, chemical resistance, abrasion resistance and durability.
