<p>Laser-writable, black-colored blends of carbonate and polyester resins are provided by the incorporation of a black colorant formulation comprising carbon black and a fatty acid metal salt. Zinc stearate is a preferred fatty acid metal salt. The black-colored resin blends can be inscribed using standard YAG lasers and maintain an excellent balance of other properties including surface aesthetics, physical properties, heat resistance, chemical resistance and processability.</p> |
