TINTABLE COATINGS FOR GLASS OPHTHALMIC LENSES |
摘要 |
This invention relates to coatings for application to glass lenses to provide a tint thereto. The coatings at a thickness of no more than 10 microns in conjunction with organic dyes conventionally used to tint organic plastic lenses will impart a visible transmission of less than 50%, preferably less than 30%. The coatings consist essentially of an alkyl siloxane containing a dipolar silane selected from the group consisting of an ester-functional silane, a hydroxy-functional silane, amino-functional silane, a carboxylic acid-functional silane, and a halide form of those silanes. |
