The present invention describes solvent and water based primer compositions comprising carboxylated polyolefins that have been modified with one or more polyfunctional alcohols. The carboxylated polyolefins are obtained by the reaction of polyolefins with unsaturated esters, unsaturated acids, unsaturated anhydrides, acrylic monomers, or mixtures thereof. The carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols.
