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 methane compounds and yellow compounds of the methine and anthraquinone classes that block ultraviolet light and/or violet-blue light transmission through ophthalmic lenses.

Copolymerizable methine and anthraquinone compounds and articles containing them

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

UV-absorbing polymers and copolymers suitable for Composition into sunscreens for the protection of human skin. The UV-absorbing chromophoric monomers chosen are simple and easily synthesized. With the correct choice of chromophoric monomer or mixture of monomers, protection against UV-A radiation or against both UV-A and UV-B radiation can be achieved. With the correct choice of comonomer, copolymers produced as aqueous latex emulsions or as Polyethylene Glycol solutions can also be achieved.

Polyvinyl ultraviolet light absorbers for personal care

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

This invention pertains to certain novel colorant compounds containing one or more ethylenically-unsaturated, photopolymerizable radicals that may be copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers. Suitable compositions having the present colorants copolymerized therein include, e.g., polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The present invention also pertains to processes for preparing the photopolymerizable colorant compounds. The ethylenically unsaturated colorant compounds may be suitable for use in coatings that are applied to wood, glass, metal, thermoplastics and the like.

Ethylenically-unsaturated blue anthraquinone dyes

This invention pertains to certain novel red anthraquinone colorant compounds containing one or more ethylenically-unsaturated (e.g., vinyl), photopolymerizable radicals that may be copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers. Suitable compositions having the present colorants copolymerized therein include, e.g., polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The novel colorants possess good fastness (stability) to ultraviolet (UV) light, good solubility in vinyl monomers and good color strength. The present invention also pertains to processes for preparing the photopolymerizable colorant compounds. The ethylenically unsaturated colorant compounds may be suitable for use in coatings that are applied to wood, glass, paper, metal, thermoplastics and the like.

Ethylenically-unsaturated red anthraquinone dyes

Method for preparing light-absorbing polymeric compositions

Disclosed are thermally-stable, red, anthraquinone colorants which contain one or more ethylenically-unsaturated, photopolymerizable radicals and which may be copolymerized with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The compounds possess good stability to ultraviolet light, good solubility in vinyl monomers, good color strength and thermal stability. Also disclosed are acrylic polymeric materials, i.e., polymers derived from acrylic acid esters, methacrylic acid esters and/or other copolymerizable vinyl compounds, having copolymerized therein one or more of the colorant compounds of the present invention.

This invention relates to a polycarbonate represented by the formula (I):

Process for preparing poly (2,2,4,4-tetramethyl-1,3-cyclobutylene carbonate)

The present invention relates to a polymeric composition suitable for use in films, molded articles and fibers, including microdenier fibers. The polymeric composition comprises a thermoplastic resin in an amount from about 50 weight percent to about 99.9 weight percent of the polymeric composition, and a dye composition in an amount from about 0.1 weight percent to about 50 weight percent of the polymeric composition. The dye composition contains an indanthrone compound as a major component. As used herein, indanthrone compounds are defined as compounds having the general structure represented by Formula I:
