Abstract
The object of the present invention is to provide a laminate for laser marking which is useful for forming displays or indications, for example, on the surface of sheet-like molded products made of thermoplastic resins, by suitably employing thermoplastic polymer resins for laser marking, and whose slipping property on the production process can be improved and whose blocking problem at the storage in the stacked condition can be solved. In an aspect of the present invention, there is provided a laminate for laser marking comprising a layer (A) and a layer (B) laminated on at least one side of layer (A), which layer (A) comprises a white or black coloring laser-marking thermoplastic resin, which layer (B) comprises a transparent thermoplastic resin and has a light transmittance of not less than 70% in the single layer, and the transparent thermoplastic resin in the layer (B) being subjected to anti-blocking treatment.
