摘要:
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.

摘要:
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. 2. In one embodiment the ophthalmic devices are made from acrylates and the light absorbing compound is an Eastman Yellow 035 MA dye.

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.

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.

摘要:
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.
