Abstract: The present invention provides solvent- and water-based primer compositions that include at least one carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof. The carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified polyolefins water-dispersible. These primer compositions are useful for significantly improving the adhesion of paints, adhesives, and inks to various plastic and metal substrates.

Abstract: The invention relates to solvent-based primer compositions containing 0.5 to 40 weight percent of a modified polyolefin and a solvent selected from the group consisting of ester solvents, ketone solvents, aliphatic solvents, aromatic solvents and mixtures thereof. The modified polyolefin is formed from an amorphous polyolefin selected from polypropylene and a propylene copolymer or a propylene terpolymer or an ethylene copolymer or terpolymer. Preferably the polyolefin is a polypropylene copolymer or terpolymer containing about 1 to about 99 mole percent ethylene, 1-butene, 1-pentene, and 1-hexene. The amorphous polyolefin has a number average molecular weight ranging from about 1,000 to 15,000 and is chemically modified with one or more unsaturated carboxylic acids selected from the group consisting of acids, esters and anhydrides. These primers are useful for significantly improving the adhesion of paints to polyolefin surfaces.
