It is an object of the present invention to provide a polyolefin resin dispersion composition in which the dispersed resin is stable to water or a hydrophilic substance, and which has an adhesive property to nonpolar substrates, in particular poorly adhesive polyolefin-based substrates whose surface has not been treated, is excellent in a coating property, exhibits an excellent adhesive property through drying and press bonding with heat at a temperature in a wide range regardless of whether the temperature is low or high, is excellent in water resistance and gasohol resistance and is less tacky. That is, the present invention provides the dispersed resin composition containing (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, and a process for producing the same.

Polyolefin resin dispersion composition and process for producing the same

A novel binder resin which attains good adhesion to various substrates such as polyolefin resins, vinyl chloride resins, polycarbonate resins, polyethylene terephthalate resins, acrylonitrile/butadiene/styrene resins, and nylon resins even by low-temperature baking and has excellent solubility in solvent. Namely, a chlorinated propylene random copolymer produced by subjecting a propylene random copolymer which is obtained by copolymerizing propylene with other alpha-olefins by using a metallocene catalyst as the polymerization catalyst and which has a melting point (Tm) of less than 115&#xb0; C. as determined with a differential scanning calorimeter (DSC) to thermally kneaded preferably at a temperature ranging from the melting point of the copolymer to 350&#xb0; C. and chlorination successively.
