Abstract

The present invention relates to solvent compositions including an effective amount of 1-chloro-3,3,3-trifluoropropene and uses thereof. In certain aspects, such solvent compositions may be applied to the surface of an article or portion of an article having an ink or ink-based marking so as to remove the ink or ink-based marking without deleteriously impacting the article or surface of the article.

Claims (22)

1. A method for removing an ink or ink-based marking from an optical lens or a surface of an optical lens comprising:

providing an optical lens having an ink or ink-based marking on at least a portion of its surface, wherein at least a portion of the lens comprises a plastic, polymeric, or elastomeric material;

applying to the portion of the surface of the optical lens with the ink or ink-based marking a solvent composition comprising an effective amount of trans-1-chloro-3,3,3-trifluoropropene and at least one C 1 -C 3 alcohol;

removing the solvent composition and the ink or ink-based marking from the surface of the optical lens.

2. The method of claim 1 , wherein the solvent composition is applied as a liquid.

3. The method of claim 1 , wherein the solvent composition is applied as a sprayable composition.

4. The method of claim 1 , wherein the solvent composition is applied to a fabric or cloth, which is then used to apply the solvent composition to the surface of an article.

5. The method of claim 1 , wherein the optical lens includes a polycarbonate material or coating.

6. The method of claim 1 , wherein the solvent composition further comprises at least one C 4 -C 6 hydrocarbon, wherein the total amount of both the C 1 -C 3 alcohol and C 4 -C 6 hydrocarbon is from greater than 0 wt % to about 10 wt %, based on the total weight of the solvent composition.

7. The method of claim 1 , wherein the C 1 -C 3 alcohol is selected from the group consisting of methanol, ethanol, isopropanol and combinations thereof.

8. The method of claim 6 , wherein the C 4 -C 6 hydrocarbon is selected from the group consisting of n-pentane, isopentane, cyclopentane, hexane and combinations thereof.

9. The method of claim 1 , wherein the alcohol is provided in an amount from greater than 0 weight % to about 10 weight percent, based on the total weight of the solvent composition.

10. The method of claim 1 , wherein the alcohol is provided in an amount from greater than 0 wt. % to about 5 wt. %, based on the total weight of the solvent composition.

11. The method of claim 6 , wherein the alcohol is provided in an amount from greater than about 0% to about 5% and the hydrocarbon is provided in an amount from greater than about 0% to about 5%, based on the total weight of the solvent composition.

12. The method of claim 1 , wherein trans-1-chloro-3,3,3-trifluoropropene is provided in an amount between about 1% by weight to about 99% by weight, based on the total weight of the solvent composition.

13. The method of claim 1 , wherein trans-1-chloro-3,3,3-trifluoropropene is provided in an amount between about 5% by weight to about 99% by weight, based on the total weight of the solvent composition.

14. The method of claim 1 , wherein trans-1-chloro-3,3,3-trifluoropropene is provided in an amount between about 5% to about 95% by weight, based on the total weight of the solvent composition.

15. The method of claim 1 , wherein trans-1-chloro-3,3,3-trifluoropropene is provided in an amount greater than 50% by weight, based on the total weight of the solvent composition.

16. The method of claim 1 , further comprising at least one additional component, other than a C 1 -C 3 alcohol or C 4 -C 6 hydrocarbon, selected from the group consisting of a co-solvent, an anticorrosive agent, surfactant, stabilizer, flammability suppressor, inhibitor and combinations thereof.

17. The method of claim 16 , wherein the additional component comprises a co-solvent.

18. The method of claim 16 , wherein the additional component comprises a stabilizer.

19. The method of claim 1 , wherein the solvent exhibits substantially no deleterious effect on the optical lens.
