Abstract: Provided is a binder resin composition for high-solid primer with excellent high-octane gasohol resistance, adherence, warm water resistance, moisture resistance, etc., when painting onto polyolefinic resins. The binder resin composition is for a high-solid primer characterized by formulating one set or two or more sets of mixtures selected from alcoxylated melamine with carbamate group-containing compound, alcoxylated melamine with hydroxyl group-containing compound, and isocyanate group-containing compound with hydroxyl group-containing compound, to a mixture of particular carboxyl group-containing chlorinated polyolefin with ketonic resin.

Abstract: A binder resin containing a mixture of carboxyl group containing chlorinated polyolefins and an ethylene-vinyl acetate copolymer. The binder resin is incorporated in primer formulations for application on substrates including polyolefinic materials.

Abstract: The invention provides a package of solid material of carboxylic anhydride-modified chlorinated polyolefin to be used for a binder resin for paint or primer that aims at the protection or beautiful ornament of polyolefinic resins, capable of suppressing the changes in physical properties after storing for a long term, and a method of preserving said solid material.

Abstract: The invention provides a binder resin solution for paint, primer, printing ink or adhesive with good adherence to polyolefin and excellent solvent resistance, without injuring the low-temperature fluidity and the stability of viscosity over the time of carboxyl group-containing chlorinated polyolefin.

Abstract: The invention provides a binder resin and a primer composition, paint composition, ink composition an adhesive composition with excellent gasohol resistance, adherence, weather resistance, etc. to polyolefinic resins and relates to a binder resin for polyolefinic resins comprising carboxyl group-containing chlorinated polyolefin (II), which contains not more than 2% of a component with molecular weight of 2,000 or lower and which has a ratio of weight average molecular weight (Mw) to number average molecular weight (Mn), that is the value Mw/Mn of not more than 4.

Abstract: The invention provides a novel binder resin composition. A binder resin composition characterized by comprising carboxyl group-containing chlorinated syndiotactic polyolefin resin with chlorine content of 0.1 to 40 wt. %, grafting level of &agr;,&bgr;-unsaturated carboxylic acid and/or its acid anhydride of 10 wt. % and weight average molecular weight of 30000 to 220000 and organic solvent. The carboxyl group-containing chlorinated syndiotactic polyolefin obtainable from polyolefin resin produced using metallocene compound exhibits good state of solution even if the chlorine content may be low, and is excellent in the adherence to polyolefinic prime material and the solvent resistance.
