PROBLEM TO BE SOLVED: To provide a self-absorption polymer sheet having no adhesiveness and excellent in self-absorption property and detachability to an adherend.SOLUTION: A self-absorption polymer sheet contains a polymer of monomer mixture that contains at least (A) polyfunctional urethane(meth)polyacrylate having two or more (meth)acryloyl groups in a molecule and rigidity of 10 to 70 when cured alone and (B) polyfunctional urethane(meth)polyacrylate having two or more (meth)acryloyl groups in a molecule and rigidity of 80 to 100 when cured alone, and a 90° peel force of the self-absorption polymer sheet to a borosilicate glass is 0.3 N/20 mm or less and a vertical peel force of the self-absorption polymer sheet to the borosilicate glass is 8 to 30 N. |
