    Abstract: 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. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements and possibly patterned and/or integrated with a crosstalk blocking matrix. For example, color conversion and/or assistant dyes may be used to enhance spectral regions transmitted through the color filters and shape the illumination spectrum, to improve efficiency and performance.

    Abstract: This invention relates to liquid complexes of anionic organic dyes with quaternary ammonium compounds which are homogeneous and thus substantially free of unwanted inorganic salts. Of particular interest as quaternary ammonium compounds are those which comprise alkoxylated moieties. Such complexes are formed through ionic bonds formed between the two compounds. The complexes are then removed of substantially all resultant unwanted salt formed from the cations of the dye and the counter ions of the quat so as to obtain an homogeneous liquid colorant which easily disperses within different media and which possess favorable migration and coloring characteristics. This invention also concerns methods of making the aforementioned salt-free anionic dye/quat complexes as well as methods of utilizing such complexes for dyeing thermoplastic and thermoset compositions and the incorporation of such complexes within aqueous and non-aqueous formulations and ink compositions.
