MOLDING MATERIAL AND MOLDED ARTICLE FOR LASER FUSION

摘要

A molding material or a molded article for laser fusion, characterized in that it comprises a thermoplastic resin (A) containing a rubber-reinforced resin (A1) prepared by the polymerization of a vinyl monomer in the presence of a rubbery polymer (a) or a composition (A2) composed of said rubber-reinforced resin (A1) and a (co)polymer (b) from at least one vinyl monomer, and exhibits a transmittance of a light having a wavelength of 808 nm of 5 % or more when measured as a formed specimen having a thickness of 4 mm. It is preferred that the rubbery polymer (a) dispersed in the thermoplastic resin (A) has a weight average particle diameter of 50 to 220 nm and contains particles having a particle diameter of 300 nm or more in an amount of 0 to 20 wt % relative to 100 wt % of said component (a). A laser light can transmit the molding material and the molded article, which allows the molding material and the molded article to be laser-fused with various resin moldings.
