Abstract

The present invention aims to provide a resin having an excellent solubility to alcohols, an excellent adherability to nonpolar base materials such as polyolefin, and not containing chlorine; and to provide a resin composition containing a urethane resin, not having the elimination problem of hydrochloric acid caused by external factors, having a good compatibility with a variety of components containing urethane resins, and having a good adherability to a variety of base materials, so that the resin composition can suitably be used as an ink, an adhesive, and paint. The present invention provides a block copolymer comprising a polymer block (A) mainly comprising olefin monomers and a polymer block (B) comprising vinyl monomers having hydroxy groups and other vinyl monomers copolymerizable with the vinyl monomers having hydroxy groups, in which a hydroxy value is within a range of 5 mg KOH/g to 120 mg KOH/g; a dispersion thereof; a resin composition containing the block copolymer and a urethane resin; and uses thereof.
