PRESSURE-SENSITIVE ADHESIVE COMPOSITION HAVING IMPROVED INITIAL TACK |
摘要 |
The present invention is directed to providing a pressure-sensitive adhesive with good initial tack and good adhesion at low temperature. Generally, the pressure-sensitive adhesive composition comprises (1) a carboxylic group-containing (meth)acrylic tacky polymer having a weight average molecular weight of less than 800,000 and a glass transition temperature of −100° C. to −30° C., and (2) an amino group-containing (meth)acrylic non-tacky polymer having a weight average molecular weight of from 30,000 to 100,000 and a glass transition temperature of 20° C. to 90° C. The amino group-containing (meth)acrylic non-tacky polymer (2) is present in an amount of no less than 1 parts by mass and less than 20 parts by mass on a basis of 100 parts by mass of said carboxylic group-containing (meth)acrylic tacky polymer (1). |
