  • Patent number: 5821301
    Abstract: Disclosed is a modified chlorinated polyolefin resin composition, as well as a method for producing the same, which has adhesion to polyolefin substrates without the need of steam-washing or degreasing the polyolefin surface with chlorine-based organic solvents such as trichloroethane, and which is improved in such properties as interlayer adhesion to base-coats and/or top-coats and gasohol resistance. The modified polyolefin resin composition for polyolefin resin paints comprises: a chlorinated polyolefin having an acid value of 1 to 500 mg.multidot.KOH/g, which is obtained by chlorinating a polyolefin modified with one kind, or more than one kind, of compounds selected from a group consisting of .alpha., .beta.-unsaturated carboxylic acids and/or acid anhydrides thereof in a range of 1 to 50% by weight; and a compound and/or a resin thereof having one epoxy group per molecule represented by the structural formula as described in the specification.
