Document Type and Number:
Japanese Patent JP7388931
Kind Code:
B2
Abstract:
To provide a hot-melt adhesive composition that is excellent in adhesion to a base material, in particular, adhesion to a base material in a wet state, material strength of a cured adhesive, and water absorption (water absorption speed) of a base material to which the hot-melt adhesive composition is applied.SOLUTION: A hot-melt adhesive composition contains a thermoplastic hydrocarbon resin (A), a tackifier resin (B), and a plasticizer (C). The (A) is amorphous α-polyolefin, the (B) is an aromatic resin, an alicyclic resin having a softening point of 80-150°C or their hydrogenated products, the (C) is condensed ester of glycerol or polyglycerol and a fatty acid, a content of the (C) is 2-10 mass% when the total mass of the hot-melt adhesive composition is 100 mass%, and a contact angle 10 seconds after dropping by water obtained by measuring the hot-melt adhesive composition according to JIS K 6768:1999 is 50° or less.SELECTED DRAWING: None
