ABSTRACT:
Photocurable polyester resin compositions are provided which are adapted for use in coating applications. The polyester resin compositions are air-uninhibited and are low energy photocurable at room temperature as substantially 100% solids systems. The photocurable polyester resin compositions are cured by exposure to activating light, without the necessity of incorporating any additional ingredients in the polyester compositions.
Each photocurable polyester resin composition comprises a prepolymer(A) containing maleate and/or fumarate groups, and allyl ether groups; a solvent(B) which is a non-volatile polymerizable ester of acrylic or methacrylic acid derivative; and an organic polymerization initiator(C) which is photosensitive in the presence of oxygen.
