Abstract
Official abstract text for this publication.
An object of the invention is to provide a primer composition for application between the base film and the adhesive layer of an adhesive tape that can improve the adhesion between the base film and the adhesive layer of the adhesive tape and an adhesive tape prepared by using the primer composition. A primer composition, comprising 100 parts by mass (as solid matter) of a graft polymer of a natural rubber graft-polymerized with 15 to 65 mass % of methyl methacrylate and 25 to 300 parts by mass of a carboxyl group-modified acrylonitrile butadiene rubber.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adhesive tape, prepared by applying a primer composition between a base film mainly made of a polyvinyl chloride having 30 to 60 parts by mass of a softening agent and an adhesive layer mainly made of a natural rubber and a graft polymer of 70 mass % of a natural rubber graft copolymerized with 30 mass % of methyl methacrylate laminated on at least one face of the base film; and wherein the primer composition, comprising 100 parts by mass (as solid matter) of a graft polymer of a natural rubber graft-polymerized with 30 to 50 mass % of methyl methacrylate and 100 to 200 parts by mass of a carboxyl group-modified acrylonitrile butadiene rubber; and the carboxyl group-modified acrylonitrile butadiene rubber has a nitrile content of 27 to 40% and carboxyl group-modification rate of 0.5 to 7 mass %, and a solid matter concentration of the primer composition after dilution with solvent is 1 to 20 mass %, and a solution viscosity of the solution of the primer composition diluted with a solvent is 1 to 500 MPa·s, and the primer composition contains a graft polymer having a Mooney viscosity (MS.sub.1+4, at 100.degree. C.) of 80 to 150 or contains additionally 1 to 10 parts by mass (as solid matter) of a surfactant with respect to 100 parts by mass (as solid matter) of the graft polymer. 2. The adhesive tape according to claim 1 , wherein the tape is used for binding of electric wires.
