ABSTRACT:
A thermosetting resin composition particularly suitable for surface coatings, including metals, paper and paperboard, and especially those papers subsequently converted into shaped paperboard products, e.g. paper plates and folded cartons, with a high gloss, water and oil resistant surface coating. The composition is suitable also as both an adhesive and coating in metallizing substrates by the transfer of metallic particles from a transfer agent to the substrate. When formulated without solvents or dispersants it is suitable for use as a casting composition or as a molding material. The composition comprises a polymer or copolymer containing carboxylic acid groups; an epoxy compound containing an average of more than one epoxide group per molecule; an ammonium or phosphonium base or salt thereof; and a monomeric carboxylic acid or inorganic acid which extends the useful working life of the composition and imparts a superior glass to the surface of the finished product.
