Title:
PVC-BASED PRESSURE-SENSITIVE ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP3945942
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a PVC-based pressure sensitive sheet having an adhesion strength of 30 gf/10 mm or more, preferably, of 50 gf/10 mm or more in response to the growing demands for higher adhesion strength.
SOLUTION: A PVC-based pressure sensitive adhesive sheet is prepared by forming into the sheet form a composition which is a mixture of 100 pts.wt. of a vinyl chloride-based polymer, 5-80 pts.wt. of a plasticizer, 3-20 pts.wt. of a tackifier and 1-10 pts.wt. of a modifier, then by annealing this sheet. A setting temperature of the annealing shall be from the softening point of the tackifier to the softening point thereof plus 55°C.
