To provide a molding resin composition which has adequate hardness while keeping the adhesiveness to polyvinyl chloride, and is excellent in flexibility (low-temperature bendability) at low temperature (-40°C), and whose components do not separate when the molding resin composition is melted for a long time, and which can be used suitably as a hot-melt material.

The molding resin composition contains aromatic polyester (a), a tackifier (b), a polyol compound (c) having two or more hydroxyl groups in one molecule thereof, and a core-shell particle (d). The core-shell particle (d) comprises a core comprising silicone-acrylic composite rubber and a shell comprising a vinyl compound having a polar group (x). The molding resin composition contains 1-50 parts mass core-shell particle (d) based on 100 parts mass aromatic polyester (a).
