<p><P>PROBLEM TO BE SOLVED: To provide a water-dispersible polyolefin resin composition which forms a smooth coating film with a solidified surface when applied to a substrate and is excellent in storage stability. <P>SOLUTION: The water-dispersible polyolefin resin composition comprises 100 pts.mass of a combination of (A) 5-70 mass% of a poly(1-butene) resin having (i) a meso pentad fraction [mmmm] of 20-80 mol% and (ii) a weight average molecular weight (Mw) measured by GPC of 10,000-1,000,000 or (A') 5-70 mass% of a polypropylene resin having (i) a meso pentad fraction [mmmm] of 20-60 mol% and (ii) a limiting viscosity [η] measured at 135°C in tetralin of 0.1-15 dl/g with (B) 95-30 mass% of water; (C) 0.01-1.00 pts.mass of a surfactant; (D) 0.01-1.00 pts.mass of a water-soluble polymer compound; and (E) 2-200 pts.mass of a water-insoluble organic solvent. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
