Abstract
A laser-debondable composition includes an acrylic resin, a light-shielding material, an additive, and a solvent. Wherein, the acrylic resin includes at least one nitrogen-containing organic group selected from a group consisting of tertiary amino groups and secondary amino groups, an organic group having a cyclic ether group, and an organic group having a hydroxyl group, and the additive includes at least one adhesion promoter. The laser-debondable composition has excellent adhesion ability to a substrate, attachability, and solvent resistance.
