Abstract
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.
