Abstract
The present invention discloses an ultraviolet light curable decorative metallic composition and method for making such a composition that may be used to produce a decorative metallic coating on a substrate. The composition comprises a novolac epoxy acrylate prepolymer, a photoinitiator and a metallic pigment. The disclosed composition does not contain any significant amount of volatile organic solvents.
Claims14
A photocurable decorative metallic composition comprising:
- a novolac epoxy acrylated oligomer present in an amount of 20% to 45% of the weight of the metallic composition;
- an isobornyl acrylate monomer present in an amount of 15% to 40% of the weight of the metallic composition;
- a photoinitiator present in an amount of 4% to 14% of the weight of the metallic composition;
- metallic pigment present in an amount of 5% to 40% of the weight of the metallic composition;
- and
- a flow promoting agent present in an amount of 0% to 8% of the weight of the metallic composition.

A method for coating a substrate with a photocurable metallic composition, the method comprising:
- applying the metallic composition to the substrate, wherein the metallic composition comprises:
- a novolac epoxy acrylated oligomer present in an amount of 20% to 45% of the weight of the metallic composition;
- an isobornyl acrylate monomer present in an amount of 15% to 40% of the weight of the metallic composition;
- a photoinitiator present in an amount of 4% to 14% of the weight of the metallic composition;
- metallic pigment present in an amount of 5% to 40% of the weight of the metallic composition;
- a flow promoting agent present in an amount of 0% to 8% of the weight of the metallic composition;
- and
- illuminating the metallic composition with UV light such that the metallic composition is caused to form the coating as it cures.
