Chlorinated polyolefin resin composition

A chlorinated polyolefin resin composition, comprising:

• a component (A):
• a polyolefin resin A having a melting point (TmA) obtained with a differential scanning calorimeter (DSC) of 90 to 160° C., and
• a component (B):
• a polyolefin resin B having a melting point (TmB) obtained with a differential scanning calorimeter (DSC) of 50 to 130° C.,
• wherein at least one of the component (A) and the component (B), or a copolymer of the component (A) and the component (B) is a chlorinated polyolefin resin, where |TmA−TmB|≥5° C.;
• wherein the component (B) is a propylene block copolymer comprising a propylene component and another α-olefin component, and the propylene copolymer comprises 60 mass % or more of propylene-derived constituent units;
• and
• wherein the component (A) is a copolymer, and the component (A) comprises 60 mass % or more of propylene-derived constituent units.
