RESIN COMPOSITION FOR WHITE MARKING

A resin composition which comprises a thermoplastic resin, a non-terpenic higher fatty acid or a derivative thereof, and a black dye/pigment. The higher fatty acid or derivative thereof may be a C12-30 saturated higher fatty acid, a metal salt thereof, etc. The thermoplastic resin may be an acrylic...

More Information
Summary:A resin composition which comprises a thermoplastic resin, a non-terpenic higher fatty acid or a derivative thereof, and a black dye/pigment. The higher fatty acid or derivative thereof may be a C12-30 saturated higher fatty acid, a metal salt thereof, etc. The thermoplastic resin may be an acrylic resin or styrene resin. The black dye/pigment may be carbon black, etc. The resin composition may contain a dye/pigment such as titanium oxide. Use of the resin composition enables a bright white marking to be formed by irradiation with a laser beam. Cette composition à base de résine comprend une résine thermoplastique, un acide gras supérieur, non terpénique, ou un dérivé de celui-ci, et un colorant/pigment noir. L'acide gras supérieur, ou un dérivé de celui-ci, peut être un acide gras supérieur saturé en C12-30, ou un sel métallique de celui-ci, etc.. La résine thermoplastique peut être une résine acrylique ou une résine styrène. Le colorant/pigment noir peut être du noir de charbon, etc. Cette composition peut contenir un colorant/pigment tel que de l'oxyde de titane. L'utilisation de cette composition à base de résine permet la formation d'un marquage blanc brillant par rayonnement à l'aide d'un faisceau laser.
