This invention relates to polymerizable ultraviolet light absorbers and yellow colorants and their use in ophthalmic lenses. In particular, this invention relates to polymerizable ultraviolet light absorbing methine compounds and yellow compounds of the methine and anthraquinone classes that block ultraviolet light and/or violet-blue light transmission through ophthalmic lenses.

Ophthalmic devices are provided having a violet-light vertical cut-off filter abruptly absorbs light between the wave lengths of between approximately and 400 nm and 450 nm such that a curve when plotted as percent transmission versus wavelength has the shape as depicted in FIG.. In one embodiment the ophthalmic devices are made from acrylates and the light absorbing compound is an Eastman Yellow 035 MA dye.

Ophthalmic devices having a highly selective violet light transmissive filter and related methods

Polymerizable light absorbing azo dyes are disclosed useful as monomers in the formation of devices such as, but not limited to ocular lenses. Specifically, intraocular lenses (IOL) are disclosed wherein one or more of the light absorbing dye is covalently bonded to other structural polymers though ethylene unsaturated groups. The resulting IOLs possess light absorbing properties without significant amounts of free (un-bound) azo dye molecules present in the final structural polymer matrix.

Copolymerizable azo compounds and articles containing them

Disclosed are polymer blends comprising a mixture of The polymer blends exhibit improved color, especially when used as a component of a polyester/polycarbonate blend.

Polymer blends

Disclosed are stabilized aliphatic polyester compositions comprising an aliphatic polyester, a HALS, and a tris-aryl-S-triazine UV absorber that show low embrittlement, haze formation, and discoloration during weathering. Also disclosed are aliphatic polyester compositions comprising aliphatic polyester, a hindered amine light stabilizer, a triazine UV absorber, and a phosphite that exhibit low color prior to weathering but retain good clarity, color, and excellent impact strength after exposure to weathering conditions. The aliphatic polyester compositions may be used prepare shaped articles such as, for example, films, sheets, bottles, tubes, profiles, fibers, and molded articles.

Stabilized aliphatic polyester compositions

A method for incorporating a UV light absorbing compound into a polyester prepared using direct esterification of reactants selected from a dicarboxylic acid and a diol. The method comprises reacting the reactants in an esterifying reactor under conditions sufficient to form an esterified product including at least one of an ester, an oligomer, or mixture having an ester and a mixture of low molecular weight polyester; polymerizing the esterified product in a polycondensation reactor to form a polyester; and adding the UV absorbing compound to the esterified products when at least 50% of the carboxy groups initially present in the reactants have been esterified to obtain a yield of UV absorbing compound incorporated into the polyester of greater than 25%. Articles utilizing the UV protected polyester prepared by the method of the invention are additionally disclosed.

Process for adding methine UV light absorbers to PET prepared by direct esterification

The present invention is a method for efficiently incorporating a nitrogen containing methine light absorber into a polyester resin.
