LASER-MARKING LAMINATED STRUCTURE AND LASER-MARKED LAMINATED STUCTURE

摘要

A laser-marking laminated structure has at least a base layer (2), a masking layer (3) capable of being removed by irradiation with a laser beam, and an OP layer (4) formed in that order on a support element (1). The base layer and the masking layer are colored layers having colors distinctly different from each other in lightness. The laser-marking laminated structure is irradiated with a laser beam in a desired pattern including characters to remove portions of the masking layer (3) and the OP layer (4) corresponding to the pattern so that the pattern is displayed clearly on the laser-marking laminated structure because of the contrast between the color of the base layer (2) and that of the masking layer (4).
