Document Type and Number:
Japanese Patent JP6371615
Kind Code:
B2
Abstract:
This adhesive composition includes: at least one block copolymer (A) selected from X-Y-X-type hydrogenated styrene-based block copolymers and X-Y-type hydrogenated styrene-based block copolymers; a softening agent (B) which is liquid at room temperature (23˚C); a terpene-based tackifier resin (C); and an aromatic tackifier resin (D). The adhesive composition respectively includes, per 100 parts by mass of the block copolymer (A), at least 10 but not more than 300 parts by mass of the softening agent (B), at least 1 but not more than 30 parts by mass of the terpene-based tackifier resin (C), and at least 1 but not more than 50 parts by mass of the aromatic tackifier resin (D). The ratio (the content of the terpene-based tackifier resin (C)/the content of the softening agent (B)) of the content of the terpene-based tackifier resin (C) to the content of the softening agent (B) is at least 0.05 but not more than 0.70.
