摘要： The present invention concerns a polarizer for visible light, comprising a polyvinyl alcohol-based polarizing element wherein not less than 60% of dichromophore is iodine, and a protective film. The said polarizing element has at least three absorption bands in an ultraviolet region of 210 nm to 400 nm and also has a UA value of not smaller than 4.0 which value represents ultraviolet absorption characteristics. Consequently, the polarizer of the invention possesses both superior polarization characteristics and high heat and humidity resistance. The polarizer of the invention having these characteristics is used for liquid crystal display and is suitable particularly for such uses as display in watches and electronic calculators, terminal dispaly in personal computers and word processor, picture display in portable television sets, and display in automobiles and aircraft.

摘要： A method of treating a synthetic fiber-containing knitted or woven fabric, wherein a synthetic fiber fabric or a blended fabric of synthetic and other fibers is treated with an aqueous mixture of a hydrophilic and thermally reactive urethane prepolymer with its terminal isocyanate groups blocked and (an) organopolysiloxane. This treatment is good for imparting to thermoplastic synthetic fiber goods a durable effect to prevent melting by sliding friction, and, when applied to the treatment of sportswear, it is useful for protecting players from troubles resulting from melting of clothing by friction caused by sliding attempts.
