PURPOSE: A hot melt adhesive composition is provided to improve the durability and the adhesive property of the composition compared to a conventional adhesive composition, and to secure the fast drying time and the environment-friendly property. CONSTITUTION: A hot melt adhesive composition for inner sheets of a photo album contains 20~50 parts of styrene block copolymer-based resin by weight, 20~50 parts of tackifying resin by weight, 5~30 parts of viscosity modifier by weight, and 1~3 parts of oxidation stabilizer by weight. The styrene block copolymer-based resin preferred has melting index of 5~30 grams per 10 minutes at 200 deg C. The tackifying resin is selected from the group consisting of an aliphatic petroleum resin, an aromatic petroleum resin, a rosin resin, a rosin ester resin, a terphene resin, a terphene phonol resin, a hydrogenated resin, and an alkyl phenol resin. |
