Title
(EN) Hot melt adhesive
Abstract
(EN)

The present invention provides a hot melt adhesive being highly environmentally-friendly, and as well having sufficient tackiness, adhesion, thermal stability and the like. The present invention relates to a hot melt adhesive comprising (A) a polar functional group-modified conjugated diene-based polymer, (B) an aliphatic polyester-based resin, and (C) a tackifier resin.
