摘要

Provided is an acrylic film for punching excellent in transparency and free from breakage or whitening even if it is punched. The present invention is an acrylic film for punching containing a polymer (C) containing a di(meth)acrylate (A) unit represented by general formula (1) below and a mono(meth)acrylate (B) unit:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-CH 2 -CR 1 -COO-(X) n -COCR 1 -CH 2 -€ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein (X) represents at least one repeat unit selected from C 2 H 4 O, C 3 H 6 O and C 4 H 8 O, the molecular weight of (X) n is 500 or more; and R 1 represents H or CH 3 .
