    摘要： There is provided a laminate for laser marking which is useful for forming displays, for example, on the S-shaped surface of sheet-like molded products made of thermoplastic resins, by suitably employing a thermoplastic polymer composition for laser marking. The present invention relates to a laminate for laser marking, comprising: a layer A comprising a multi-color developing laser marking thermoplastic polymer composition capable of producing markings having two or more different color tones by irradiating thereto two or more laser lights having different energies from each other, the composition satisfying the following requirements (1) and (2): (1) comprising a chromatic colorant, a black substance capable of being dissipated by itself or discolored when exposed to the laser lights, and a thermoplastic polymer at the following mixing ratio, and (2) containing the chromatic colorant and the black substance in amounts of from 0.001 to 3 parts by weight and from 0.01 to 2 parts by weight, respectively, on the basis of 100 parts by weight of the thermoplastic polymer; and a layer B formed on at least one surface of the layer A, the layer B comprising a transparent thermoplastic resin, and exhibiting a light transmittance of not less than 70% as a single layer.

    摘要： The objective of the present invention is to provide a chromatic coloring agent for multicolor laser marking, capable of forming clear markings having two or more different color tones when two or more laser beams having different energy levels are irradiated onto different places of a molded article, a composition for multicolor laser marking, for example, capable of forming a chromatic marking derived from the chromatic coloring agent and a white marking on the surface of a molded article whose base color is black or dark-color based color, a laser marking method, a multicolor-marked molded article and the like. The present chromatic coloring agent has an exothermic peak in the range of 360° C. or higher and 590° C. or lower, as measured by differential thermal analysis. The present laser marking composition comprises a chromatic coloring agent, a black substance (carbon black or the like) which is itself depleted or discolored by receiving a laser beam, and a polymer, and the contents of the chromatic coloring agent and the black substance are respectively 0.001 to 3 parts by mass and 0.01 to 2 parts by mass with respect to 100 parts by mass of the polymer.
