GRAFT NATURAL RUBBER PRESSURE-SENSITIVE ADHESIVE AND PRESSURE-SENSITIVE ADHESIVE TAPE USING IT

摘要

A graft natural rubber pressure-sensitive adhesive containing in a latex state a copolymer formed by graft polymerizing a vinyl polymer onto a natural rubber having a protein content of 0.1 % by weight or less in terms of nitrogen, and a pressure-sensitive adhesive tape comprising a support having coated on at least one surface thereof the pressure-sensitive adhesive. The pressure-sensitive adhesive is excellent in various properties such as film-forming property, pressure-sensitive characteristics, water resistance, and electrical insulation property.
