<P>PROBLEM TO BE SOLVED: To provide a light absorption resin composition for laser welding which absorbs an irradiated laser beam, generates uniform exothermic heat, and performs stabilized laser welding, and in which a bonding welding portion can hold transparency, and to provide a light absorption resin molded product. <P>SOLUTION: The light absorption resin composition for laser welding includes a polymeric dispersant having at least 30°C of a glass transition temperature, and a laser beam absorption fine particle, wherein the laser beam absorption fine particle is one or more sorts of fine particles chosen from the group consisting of strontium metavanadate shown by the general formula SrVO<SB POS="POST">3-X</SB>(0≤X≤1), niobium strontium titanate shown by the general formula Sr(Ti, Nb)O<SB POS="POST">3-X</SB>(0≤X≤1), and calcium metavanadate shown by the general formula CaVO<SB POS="POST">3-X</SB>(0≤X≤1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
