Abstract: PURPOSE:To enable the re-utilization of an article by perfectly removing a cured film comprising an org. compound, by immersing the article made of a resin having the cured film in an aqueous surfactant solution before immersing the same in an alkali aqueous solution. CONSTITUTION:In removing the cured film applied to an article made of a resin as surface processing for enhancing the function of said article or the film adhered to a holding jig at the time of various coating processings, the article is at first immersed in an aqueous surfactant solution. The aqueous surfactant solution in this case is prepared by dissolving one or more of an anionic, noionic or cationic surfactant in water. Next, the article after treatment is immersed in an alkali aqueous solution of lithium hydroxide, sodium hydroxide or ammonia to perfectly remove the adhered substance without imparting damage to the article.

Abstract: PURPOSE:To provide a lens which is highly resistant to weather and light and is effective particularly for decreasing the yellowing when irradiated with UV rays by coating a transparent film having a specific value or below of coeff. of oxygen permeability on the surface of the high refractive index resin lens having an arom. ring at the main chain and/or side chain. CONSTITUTION:The composite body is obtd. by coating the transparent film consisting mainly of the org. polymer having cm .cm/cm .sec.cmHg coefft. of oxygen permeability on the surface of the high refractive index resin lens having the arom. ring at the main chain and/or side chain. PVA, polyvinyl acetate and cellulose are preferably used for the ease of the film formation as the more specific examples of the transparent material to be used. There is substantially no effect of the coating and the improvement in the light resistance is not expected if the coefft. of the oxygen permeability of the org. polymer used for coating exceeds 100X10 cm .cm/cm .sec.cmHg. The transparent film having cm .cm/cm .sec.cmHg is further preferable in order to provide the effect with the thinnest possible film.
