Abstract
A hot melt composition comprising a specific ratio of: (a) an ethylene copolymer resin; (b) a modified aromatic petroleum resin having a specific weight-average molecular weight and produced by copolymerization using a Friedel-Crafts catalyst from a specific ratio of: (1) a polymerizable component of the thermal cracked oil fraction having boiling points in a specific range and obtained by the thermal cracking of petroleum hydrocarbons, and containing vinyltoluene and indene at specific contents, (2) a turpentine oil having a specific diene value, and (3) a phenol compound; and (c) a wax. It is possible to develop a hot melt composition having excellent heat stability and improved adhesion resistance to heat, which can be used as hot melt coating, printing ink, adhesive, and sealant, etc.
