A resin composition, which is obtained by quaternary salt-formation reaction, in the presence of a tertiary amine, of a copolymer and an amine-modified epoxide resin. Also disclosed herein is a water-borne coating comprising the resin. The coating composition can form superior coating film in surface appearance, adhesion, fabrication, coating film hardness, yellowing resistance and retort resistance, and has good coatability, and low organic solvent content.

Resin composition for water borne coatings and water borne coating composition

A coating composition which comprises (A) an actinic radiation curable resin, which is the ring-opening addition reaction product of (a) a polyester resin having hydroxyl functionality and (b) a compound having both a cyclic ether group and a (meth)acryloyl group, and preferably (B) at least one compound having at least one radical-polymerizable unsaturated group in a molecule. The composition also preferably comprises (C) a photopolymerization initiator and (D) photosensitizer. A process for obtaining the composition and the coating of metal substrates are also disclosed, as well as coated metal substrates that are particularly useful as cans for beverages, soft drinks, juices, and other food products. The coating compositions and the resulting cured coatings and coated substrates exhibit improved processability, adhesivity, hardness, mar resistance, appearance and retort resistance.

Radiation curable coating compositions

Disclosed is a coating composition for metal coating, said coating composition containing (A) at least one of an epoxidized polybutadiene resin and an epoxy group-containing polyhydric phenol-modified epoxidized polybutadiene resin, and (B) at least one of a capped epoxy resin and a methylol group-containing capped epoxy resin.

Coating of epoxidized polybutadiene and bisphenol-capped epoxy resin

Disclosed is a can interior coating composition which contains (A) a modified bisphenol based epoxy resin formed by introducing at least one of a functional group represented by the following formula: ##STR1## where R is a bivalent aliphatic hydrocarbon group having 1 to 4 carbon atoms, into a molecular terminal of a bisphenol based epoxy resin having an epoxy equivalent of 180 to 7,000 and a number average molecular weight of 350 to 10,000, and (B) a resol phenol resin obtained by reacting the modified bisphenol based epoxy resin (A) with formaldehydes in the presence of a basic catalyst.
