Abstract: PURPOSE:To obtain the subject resin composition excellent in long-term light resistance by blending a cerium-containing zirconia particle as an ultraviolet absorber excellent in ultraviolet screening and durability and having a low bleeding property. CONSTITUTION:A zirconia particle containing preferably 1-50mol%, more preferably 2-30mol% cerium produced, e.g. by adding a base such as aqueous ammonia to a mixture solution of salts of zirconium and cerium, carrying out coprecipitation by neutralization and subsequently crystallizing the resultant material under heating in a pressure vessel, i.e., the hydrothermal crystallization method is added to a resin in a form of a slurry prepared, e.g. using a kneader having a vacuum-line in a ratio of 1-50wt.%, preferably 1-30wt.% based on the total amount of the resin composition. The zirconia particle is kneaded into the resin while removing the solvent, thus obtaining the objective resin composition excellent in light resistance.

Abstract: PURPOSE:To obtain the title film having improved abhesiveness, excellent transparency and mechanical characteristics and being useful for light packaging films for medicines, foods, etc., by copolymerizing a polyester with two specified dicarboxylic acid components at a specified ratio. CONSTITUTION:This polyester film is obtd. by copolymerizing an acid component comprising terephthalic acid, an arom. dicarboxylic acid contg. a metal sulfonate group (e.g., 5-sodium sulfoisophthalic acid) and a 4-20C aliph. dicarboxylic acid (e.g., succinic acid) and a diol component consisting of alkylene glycols at a ratio wherein said acid component satisfies formula I (wherein X is a molar ratio of the arom. dicarboxylic acid contg. a metal sulfonate group to terephthalic acid) and formula II (wherein Y is a molar ratio of the 4-20C aliph. dicarboxylic acid to terephthalic acid). By using said film, adhesiveness is improved and transparency and mechanical characteristics are excellent, so that the film is suitably used for packaging medicined and foods, self-adhesive tapes, belt-shaped strings, etc.
