A tackifier resin is a reaction product of rosins (A), a ring structure-containing compound (B) capable of reacting with the rosins, and an alcohol (C).
First claim
Opening claim text (preview).
What is claimed is: 1. A tackifier resin being a reaction product of: rosins (A), ring structure-containing compound (B) capable of reacting with the rosins, and an alcohol (C), wherein the rosins (A) are a non-modified rosin, and wherein the ring structure-containing compound (B) is a (meth)acrylate having a ring structure. 2. The tackifier resin according to claim 1 , wherein the ring structure-containing compound (B) contains a compound having an alicyclic group containing two or more alicyclic rings and/or a compound having an aromatic group containing one or more aromatic rings. 3. The tackifier resin according to claim 1 , wherein the ring structure-containing compound (B) contains a compound having an isobornyl group. 4. The tackifier resin according to claim 1 , wherein the ring structure-containing compound (B) contains a compound having a benzyl group. 5. A pressure-sensitive adhesive composition comprising: the tackifier resin according to claim 1 , and a (meth)acrylic resin.
