Abstract: Disclosed herein are a coating composition and a coating method for producing imitation pearls. The coating composition comprises pyroxylin, camphor, an ester-based solvent and a pigment wherein the ester-based solvent consists of a mixture of acetone and ethyl acetate and a mixture of butyl acetate and amyl acetate or is a mixture of ethyl acetate and butyl acetate. The coating method is carried out by coating imitation pearl beads twice or more with the coating composition. Specifically, the imitation pearl beads are sequentially subjected to first coating, second coating and third coating. Also, the imitation pearl beads are repeatedly coated with one composition selected from primer, intermediate and top coating compositions. Also, the imitation pearl beads are repeatedly coated twice or more with two compositions selected from primer, intermediate and top coating compositions.

Abstract: A cellulose ester film is disclosed which comprises a polyhydric alcohol ester, which is an ester of one or more kinds of monocarboxylic acids with an aliphatic polyhydric alcohol, wherein the cellulose ester film has a water vapor transmission rate of from 20 to 260 g/m2·24 hours measured under conditions of 25° C. and 90% RH.

Abstract: The invention herein provides a method to improve retention of tensile properties upon aging in poly(trimethylene terephthalate) cast film. The method involves first nucleating the poly(trimethylene terephthalate) resin prior to film formation and controlling the quench temperature during casting of the film. The quench temperature should be controlled to a temperature in the range of from about 10° C. below the Tg of the poly(trimethylene terephthalate) to about 15° C. above the Tg of the poly(trimethylene terephthalate).
