Claims
- 1. A method of decorating a metallic ornament with elements resembling precious or semi-precious stones comprising: applying a photopolymerizable composition comprising 70 to 90 wt. % of a methacrylate; 0.03 to 5 wt. % of a dye and pigment; 0.05 to 2.0 wt. % of a photoinitiator and activator; and 9 to 25 wt. % of a filler to the metallic ornament to be decorated and photopolymerizing the photopolymerizable composition to produce an ornament with elements resembling precious or semi-precious stones.
- 2. The method according to claim 1, wherein the methacrylate has at least two methacrylate groups.
- 3. The method according to claim 2, wherein the methacrylate is selected from the group consisting oftetraethylene glycol dimethacrylate, diethylene glycol dimethacrylate, ethylene glycol dimethacrylate, polyethylene glycol dimethacrylate, butanediol dimethacrylate, hexanediol dimethacrylate, decanediol dimethacrylate, dodecanediol dimethacrylate, Bisphenol-A-dimethacrylate, trimethylol propane trimethacrylate, and mixtures thereof.
- 4. The method according to claim 2, wherein the methacrylate is selected from the group consisting oftriethylene glycol dimethacrylate, 2,2-bis-4-(3-methacryloxy-2-hydroxy-propoxy)-phenyl propane, a urethane methacrylate having at least two methacrylate groups, and mixtures thereof.
- 5. The method according to claim 2 wherein the composition further comprises a dye, a pigment, or a mixture thereof.
- 6. The method according to claim 5 wherein the filler is selected from the group consisting of quartz powder, glass powder, glass ceramic powder, aluminum oxide, silicon oxides, finely divided silica, and mixtures thereof.
- 7. The method according to claim 5 wherein the composition further comprises a photointiator.
- 8. The method according to claim 7, wherein the photoinitiator is selected from the group consistion ofbenzophenone, a benzophenone derivative, benzoin, a benzoin derivative, an α-diketone, an acyl phosphine oxide, camphor quinone, and mixtures thereof.
- 9. The method according to claim 1, further comprising treating the metallic ornament with an adhesion promoter prior to applying the photopolymerizable composition to the metallic ornament.
- 10. The method according to claim 1, wherein the composition comprises:80 to 90 wt. % methacrylate and 9 to 19 wt. % filler.
