发明名称 COMPOSITION FOR FILM WHICH IS PROVIDED WITH PRISM-TYPE RETROREFLECTIVE STRUCTURE ON SURFACE
摘要 Provided is a composition for use in producing a film having a prism type retroreflection structure, the composition being capable of favorably forming a prism type retroreflection structure by thermal transfer, while being superior in weather resistance and transparency and the film having breakage resistance. The composition contains: (A) an acrylic polymer produced by polymerizing (a-2) a monomer component in the presence of (A-1) a crosslinked acrylic polymer; and (B) a thermoplastic acrylic polymer, the composition having a fluidity (MFR: measured under heating at 230°C and compression at 37.3 N) of 1 to 14, and having a gel content of 25 to 50% by weight with respect to 100% by weight in total of the acrylic polymer (A) and the thermoplastic acrylic polymer (B).
