HIGHLY TACKIFIED ACRYLATE PRESSURE SENSITIVE ADHESIVES

摘要

The present invention relates to a radiation crosslinkable pressure sensitive adhesive precursor comprising:
a) an acrylate base polymer;
b) a co-polymerized type (II) photocrosslinker, in a amount greater than 0.05 parts by weight per 100 parts by weight of acrylate base polymer;
c) a co-polymerized hydrogen-donating monomer; and
d) a tackifying resin, in an amount greater than 40 parts by weight per 100 parts by weight of acrylate base polymer. The present invention is also directed to a method of preparing a radiation crosslinked pressure sensitive adhesive.
