Solvent compositions including trans-1-chloro-3,3,3-trifluoropropene and uses thereof

摘要

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.

主权项

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 C1-C3 alcohol; removing the solvent composition and the ink or ink-based marking from the surface of the optical lens.
