Patent ID: 8519046

Claim:
A dispersed resin composition comprising: (a) a polyolefin resin; (b) a (meth)acrylic acid homopolymer or copolymer having a side chain comprising an esterified alkyl group; (c) a basic substance; and (d) water or a hydrophilic substance, wherein the (a) polyolefin resin is a modified polyolefin resin comprising 60 mol % or more of a propylene component, and is modified by one or more polarity-imparting agents comprising a (meth)acryl compound comprising at least one (meth)acrylate ester represented by formula (I) in an amount of 20% by weight or more: CH 2 ═CR 1 COOR 2 (I), where R 1 is H or CH 3 , R 2 is C n H 2n+1 , and n is an integer of 1 to 18; and the (b) (meth)acrylic acid homopolymer or copolymer comprises an ester group and is obtained by bulk polymerizing (i) (meth)acrylic acid, or (i) (meth)acrylic acid and (ii) a monomer having an unsaturated bond copolymerizable with said (meth)acrylic acid, simultaneously with esterifying in alcohol having 3 or more carbon atoms and a straight or branched structure.
