Acrylic pressure sensitive adhesive composition and pressure sensitive adhesive tape |
摘要 |
<p>Provided is an acrylic pressure sensitive adhesive composition excellent in pressure sensitive adhesive characteristics and removability and a pressure sensitive adhesive tape using the acrylic pressure sensitive adhesive composition. An acrylic pressure sensitive adhesive composition containing an acrylic polymer obtained by at least copolymerizing a (meth) acrylic acid alkyl ester with an alkyl group having 2 to 14 carbon atoms and a carboxyl group containing unsaturated monomer copolymerizable with the (meth) acrylic acid alkyl ester, and tackifier resins, wherein the tackifier resins are respective resins each containing a natural product as a raw material, include at least 4 kinds of the resins different in a molecular structure from one another and a content of each of the tackifier resins is in the range of 5 parts by weight or more and 20 parts by weight or less relative to 100 parts by weight of the acrylic polymer.</p> |
