Acrylic polymer release agent, release sheet, tape, and double-sided tape

Object: To provide a long-chain alkyl-based release agent useful in the production of a light release liner that can be used in a light release surface of an adhesive transfer tape. Solution: An acrylic polymer release agent according to an embodiment includes a polymerization product of a polymerizable precursor composition containing an acrylate monomer having a branched alkyl group having 24 or more carbon atoms and an acrylic monomer having a benzophenone structure. 目的：提供了一种可用于生产可在粘合剂转移带材的轻剥离表面中使用的轻剥离衬垫的长链烷基基剥离剂。解决措施：根据实施方案的丙烯酸类聚合物剥离剂包括可聚合前体组合物的聚合产物，该可聚合前体组合物包含具有支链烷基基团的丙烯酸酯单体以及具有二苯甲酮结构的丙烯酸类单体，该支链烷基基团具有24或更多个碳原子。
