A resin composition for a white marking |
摘要 |
<p>which a white marking can be clearly developed by irradiation of laser beams, comprises an acrylic resin A, a styrenic resin B, and a black dye/pigment C. Use can be made of poly(methyl methacrylate) as the resin A, a rubber-modified styrenic resin such as an ABS resin as the resin B, and a carbon black as the black dye/pigment C. The proportion of the resin A to the resin B (the former/the latter, by weight) is about 1/99 to 99/1. The proportion of the black dye/pigment C is about 0.01 to 3 parts by weight relative to 100 parts by weight of the total amount of the resin A and the resin B. The resin composition may further comprise a white dye/pigment D such as titanium oxide in 0.01 to 10 parts by weight, relative to 100 parts by weight of the total amount of the resins A and B.</p> |
