LAMINATE FOR LASER MARKING

摘要

PROBLEM TO BE SOLVED: To provide a laminate for laser marking which is high in printing density, and good in visibility and water resistance in the laminate for laser marking with a surface protective layer and a laser coloring layer.SOLUTION: A laminate for laser marking includes a laser coloring layer and a surface protective layer of a transparent plastic film on a base material. The laser coloring layer of the laminate for laser marking contains both an organic system flame retardant and a laser coupler composed of one or more kinds selected from composite oxides of copper and molybdenum and bismuth-based oxides which include neodymium.
