TRANSPARENT COLOURANTS AND COLOURANT COMPOSITIONS, AND THEIR USE

摘要

The invention relates to a colourant composition comprising in a weight ratio of from 99:1 to 10:90, preferably a weight ratio of from 95:5 to 30:70, particularly preferred a weight ratio of from 95:5 to 50:50, a pigment of average particle size from 10 to 200nm and a 1-or 2-phenylthio-substituted anthraquinones of greenish-yellow colour hue, lacking electron-rich N^(III), O^(II) and further S^(II) substituents on the anthraquinone ring. The compositions are particularly useful in patterned colour filters. Compounds wherein the 1-or 2-phenylthio group is substituted by SOR₁₀, SO₂R₁₀, SO₃R₁₀, SO₂NR₁₁R₁₂, CN, COR₁₀, COOR₁₀ or CONR₁₁R₁₂, or the anthraquinone group is substituted by SO₂NR₁₁R₁₂are also claimed, with a few exceptions. The invention also relates to a compound of Formula (III) or (IV), wherein at least one of R₁, R₂and R₃is SOR₁₀, SO₂R₁₀, SO₃R₁₀, SO₂NR₁₁R₁₂, CN or COR₁₀, or at least one of R₇, R₈ and R₉ is SO₂NR₁₁R₁₂, with the proviso that R₃ is not SO₂NH₂.;COPYRIGHT KIPO & WIPO 2010
