Provided is a means capable of realizing a surface-roughening method for modifying the surface of a resin molded article to form a surficial layer, such as a coating or plating, or to impart a function derived from the surface configuration. The method comprises adding a resin composition and performing a post-treatment and is thus simpler and easier than conventional methods. The resin composition is a composition for resin surface roughening that contains an aliphatic polycarbonate and an alkali metal salt.

Composition for resin surface roughening

General Formula (I) Provided is an all solid state secondary-battery additive comprising a polyalkylene carbonate (I) represented by general formula (I), and by providing such additive, properties such as the charge-discharge capacity and interfacial resistance of an all-solid-state secondary battery are improved. (In general formula (I), Rand Rare each a C1-10 chain-like alkylene group or C3-10 cycloalkylene group, m is 0, 1, or 2 and n is an integer of 10 to 15000, and each R, Rand m in the polyalkylene carbonate (I) chain is independently the same or different.)
