A modified polyolefin resin in which a modified component comprising an α,β-unsaturated carboxylic acid derivative having a cyclic structure is introduced into the polyolefin resin, with the object of providing a dispersion resin composition capable of maintaining dispersion stability even when the amount of the emulsifier is reduced; , It is a dispersion resin composition containing at least an aqueous dispersion medium, and the ring-opening degree represented by Formula (1) of a modified polyolefin resin is 70 or more. (1): degree of ring opening = degree of modification K x degree of ring opening R (in formula (1), the degree of modification K represents the content (% by weight) of the α,β-unsaturated carboxylic acid derivative relative to the polyolefin resin, and the ring opening ratio R is , represents the ring-opening rate (%) of the cyclic structure in the α,β-unsaturated carboxylic acid derivative.). |
