<p><P>PROBLEM TO BE SOLVED: To provide a modified polyolefin resin aqueous dispersion composition having delicately good dispersion stability in spite of being substantially free from an emulsifier component and excellent bond strength. <P>SOLUTION: The modified polyolefin resin aqueous dispersion composition substantially free from an emulsifier comprises a modified polyolefin (A) obtained by grafting 3-20 pts.mass unsaturated carboxylic acid (a2) and 4.5-40 pts.mass alkyl (meth)acrylate (a3) on to 100 pts.mass polyolefin (a1) having at least ethylene and propylene as constituting units and a density of 0.85-0.89 g/cm<SP>3</SP>and a basic compound (B) and uses, as a dispersion medium (C), water (c1) alone or at least the water of a mixed solvent of an organic solvent (c2) and water, the organic solvent being at least 50 pts. based on 100 pts. modified polyolefin (A) by mass ratio and being soluble in water in an amount of 2.5% or more. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
