Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. For example, rhodamine-based fluorescent compounds are used in matrices produced by sol gel processes and/or UV (ultraviolet) curing processes which are configured to stabilize the compounds and extend their lifetimeto provide the required emission specifications of the color conversion films. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements.

Provided are a compound represented by Formula 1, a tautomer of the compound or a salt of the compound or the tautomer, a coloring composition and a dyed article containing the compound represented by Formula 1, the tautomer of the compound, or the salt of the compound or the tautomer, and a dyeing method using the compound represented by Formula 1, the tautomer of the compound, or the salt of the compound or the tautomer. In Formula 1, X, R, Ar, n, and m1 are as defined in the specification. ##STR00001##

The present application provides a method for bluing anthocyanin, including: mixing anthocyanin with a protein to obtain a mixed solution; and bluing the anthocyanin through standing treatment of the mixed solution. The method includes no high hydrostatic pressure treatment. A concentration of the anthocyanin in the mixed solution ranges from 0.05 mM to 0.2 m. The anthocyanin is cyanidin-3-glucoside, the protein is selected from human serum albumin or lysozyme, a final concentration of the human serum albumin, if present, in the mixed solution ranges from 0.1 mM to 2 mM, and a final concentration of the lysozyme, if present, ranges from 0.8 mM to 1.5 mM. Alternatively, the anthocyanin is malvidin-3-glucoside, the protein is selected from human serum albumin or bovine serum albumin, and the final concentration ranges from 0.1 mM to 0.5 mM. A pH value of the mixed solution ranges from 5.0 to 9.0.

The disclosure relates to methods for coloring keratinous substrates using solubilized vat dyes, as well as compositions and kits suitable for carrying out the methods. The disclosure also relates to novel solubilized vat dyes.

This invention relates to heterocyclic red azo colorants for seed treatment applications. The red azo colorants contain a heterocycle that includes one nitrogen atom and one sulfur atom and are free from electron-withdrawing groups on the heterocycle. Seeds for use in horticultural/agriculture applications that are coated with the heterocyclic azo colorants provide anti-counterfeiting properties to the coated seeds. A color change phenomenon is observed when the coated seeds are exposed to an acidic material, such as vinegar, and provides evidence of the authenticity of the coated seeds. The invention also relates to agricultural formulations containing the heterocyclic red azo colorants that can be used as an anti-counterfeit agents.

Described are deuterated indole heptamethine cyanine dyes, aqueous formulations including the deuterated dyes, and methods of using the dyes and formulations for diagnosing and treating abnormal tissue, assessing tissue perfusion, determining cardiac output, determining hepatic function, or ophthalmic angiography.

A staining composition is provided with improved staining intensity. The composition comprises a vital dye and hyaluronic acid, wherein the vital dye comprises Chicago Sky Blue and Trypan Blue. The staining composition is used to stain the lens capsule during cataract surgery and provides sufficient contrast such that no air bubble needs to be injected in the anterior chamber during cataract surgery.

Embodiments of the invention relate to an apparatus, method and article of manufacturing for producing an edible multi-color ink image. In some embodiments, first and second fluids are provided where: i. the first fluid is an acidic edible and aqueous ink whose color is pH sensitive, the first fluid comprising anthocyanin-containing extract of anthocyanin-containing plant matter (ACE-ACPM), or solids of the ACE-ACPM; ii. the second fluid is an edible pH-adjusting liquid which is clear, or whose primary colorant is riboflavin or riboflavin-phosphate.

Embodiments of the invention relate to edible ink formulations comprising a fluorophore (e.g. riboflavin phosphate), articles of manufacture (e.g. an ink-jet cartridge containing any edible ink formulation(s) disclosed herein), methods for printing on a edible substrates (e.g. food or beverage) using any edible ink formulation(s) disclosed herein. Methods for manufacturing the edible ink formulation are also provided.
