Assignee:

Novartis AG - Basel

International Classification:

G02C 704

US Classification:

526279, 526245, 526311, 526328, 5263285, 5263292, 5263295, 5263297, 525100, 525101, 525106, 525474, 525479, 525937, 523106, 523107

Abstract:

This invention is directed to ophthalmic materials and ophthalmic lenses that are a co-polymerization product of a (a) hydrophilic monomer with (b) a tris(siloxy)silyl group-containing monomer, (c) a wide variety of hydrophobic monomers (both aliphatic and aromatic) and usually a (d) polyfluorinated monomer, as well as optional monomers or monomer mixtures that can include a cationic monomer, a non-aromatic hydrophobic monomer and a poly(dimethylsiloxy)silyl group-containing monomer. A contact lens prepared from such a co-polymer exhibits enhanced water content, while maintaining exceptional oxygen permeability, thereby providing a lens that can be worn comfortably for prolonged periods of time. A process for the preparation of such lenses is also disclosed.

Appl. No.:

09/879013

Inventors:

Robert Carey Tucker - Arlington Heights IL

Assignee:

Novartis AG - Basel

International Classification:

G02B 702

US Classification:

351177, 351162

Abstract:

A method of making a colored contact lens comprises printing at least one layer of a colorant onto a contact lens using a printing process selected from the group consisting of ink jet printing, electrophotographic printing, thermal transfer printing, and photographic development printing. Printing can be done directly on the contact lens, on a film in a mold where the contact lens is formed, or on a clichà pad. Multiple layers of colorants can be printed onto a contact lens.

International Classification:

C09D 11/00

US Classification:

523160, 523161

Abstract:

The present invention provides a chemical ink comprises a solvent, a binder polymer, a colorant and optionally a crosslinker. The ink of the invention has one or more of the following characteristics: a viscosity lower than about 50 centipoises; a surface tension of from about 20 mN/m to about 60 mN/m; a particle size of less than about 5 μm; prolonged stability; an appropriate color level (visible by eye); uniform drop formation; jet stability; good adhesion to contact lenses; good transfer from a mold to a lens made in the mold; and stability of ink in inkjet nozzles. The ink of the invention is useful for inkjet printing of a high-quality color image on a contact lens or a mold so as to produce a colored contact lens.
