摘要:
PROBLEM TO BE SOLVED: To provide a (meth)acrylic film having an excellent balance between film strengths at room temperature and following capability under low temperatures, and a marking film having the above (meth)acrylic film. SOLUTION: The (meth)acrylic film comprises a (meth)acrylic polymer containing a carboxylic group, a (meth)acrylic polymer containing an amino group, a polyacrylate containing a reactive functional group and having a weight average mol.wt. in the range of 1,000-4,000, and a crosslinking agent containing a functional group that reacts with the amino group or carboxyl group. The (meth)acrylic film contains the polyacrylate in the range of 0.5-30 parts by mass based on 100 parts by mass of the total amount of the (meth)acrylic polymer containing the carboxyl group and (meth)acrylic polymer containing the amino group. A marking film having the (meth)acrylic film is also provided. COPYRIGHT: (C)2009,JPO&INPIT
