<P>PROBLEM TO BE SOLVED: To find a PVC film with water-based PSA (pressure-sensitive adhesive) attached to the back side thereof, which exhibits high fixability between the PSA and the PVC film without pretreating the PVC film, wherein the PSA used in the PVC film provides a well-balanced adhesion performance including adhesion, release/peel build, PMR, and removability in applications of graphic posters. <P>SOLUTION: This adhesive sheet includes the polyvinyl chloride (PVC) film and the water-based PSA coating on the back side thereof, wherein the PSA comprises a copolymer by copolymerization of a monomer mixture including (a) from 30 wt.% to less than 70 wt.% of a 4-8C alkyl ester of acrylic acid and (b) 2-9 wt.% of (meth)acrylonitrile, wherein the polyvinyl chloride film is not corona treated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
