Abstract
According to the invention there is provided a hot melt composition comprising (A) a hydrogenated resin having a softening point ranging from 60.degree. C. to 130.degree. C., said hydrogenated resin (A) being prepared by hydrogenating a resin at a hydrogenation percentage of aromatic rings of from 10 to 90%, said resin being prepared by copolymerizing at least two components comprising (a) 100 parts by weight of cyclopentadiene or its derivative selected from the group consisting of cyclopentadiene and dicyclopentadiene and an alkyl substituent thereof and (b) 5 to 50 parts by weight of indene or its derivative selected from the group consisting of indene and an alkyl substituent thereof and (B) one or more compound selected from the group consisting of ethylene-unsaturated ester copolymers, polyester resins and waxes.
