Patent ID: 8603619

Claim:
A laser-markable, acrylic resin-based laminate comprising: a pigmented layer being made of a crosslinked acrylic resin obtained by crosslinking an acrylic resin composition with a melamine crosslinking agent and being adapted to provide the outermost surface of the laminate when attached to a substrate, the acrylic resin composition having a hydroxyl value of 10 to 100 mg KOH/g and comprising an acrylic polymer having a reactive functional group, cellulose acetate butyrate, and a pigment, a base layer laminated with the pigmented layer being made of a crosslinked acrylic resin obtained by crosslinking an acrylic resin composition with an isocyanate crosslinking agent and providing a visibly distinguishable color difference from the pigmented layer, the acrylic resin composition having a hydroxyl value of 18 to 40 mg KOH/g and comprising an acrylic polymer having a reactive functional group, a glycol compound, and a coloring material containing an acrylic resin having a reactive hydroxyl group and a pigment dispersed in the acrylic resin, and a destructible layer laminated with the base layer, being made of a crosslinked acrylic resin obtained by crosslinking a mixture of an acrylic resin composition and polymer beads with an isocyanate crosslinking agent, the acrylic resin composition having a hydroxyl value of 20 to 35 mg KOH/g and comprising an acrylic polymer having a reactive functional group, a glycol compound, and a coloring material containing an acrylic resin having a reactive hydroxyl group and a pigment dispersed in the acrylic resin, wherein the laminate has a thickness of 100 to 200 μm.
