Surface-modified synthetic resin molding

Abstract

Abstract PURPOSE:The titled molding having excellent adhesiveness and mechanical properties, obtained by the short-time pulse irradiation of the surface of the molding of a synthetic resin containing no C-N bond, etc. in the molecule with an ultraviolet laser of a specified wave range. CONSTITUTION:The surface of the molding of a synthetic resin containing no C-X bond (where X is a halogen) and C-N bond (e.g. a PP film) is treated by short-time pulse irradiation with an ultraviolet laser having a wave range of 95-255nm, under conditions of average power output of several to tens of W and a repetition frequency of 1-100Hz. This treatment will form an extremely thin modified layer of a thickness of 1mum or less on the surface of the molding without causing deterioration by light, heat, etc. of the molding, thus giving the titled molding which has adhesiveness, printability and paintability, remarkably improved without deteriorating the mechanical strength, etc.
