Abstract

PURPOSE: To impart anti-fogging properties to a molded article without losing surface gloss, by immersing a cellulosic plastic molded article such as lenses of skiing or swimming goggles in water to soften the surface of the molded article by water abosrption, and then subjecting the molded article to a saponification treatment.
CONSTITUTION: A molded article composed of a cellulosci plastic such as cellulose acetate or cellulose acetate butyrate, is immersed in water at 10°C or higher to soften the surface thereof by water abosrption. Then the molded article is saponified by treating it in a warm aq. alkaline soln. such as an aq. soln. of NaOH at 10W 70°C by a conventional method to obtain an anti-fogging plastic molded article. Water used for the above water absorption softening stage may contain further a surfactant, a water-soluble inorg. salt such as NaCl and/or a water-soluble plasticizer such as ethanol.
