TRANSPARENT COLOURANTS AND COLOURANT COMPOSITIONS, AND THEIR USE

摘要

the present invention the average particle size of the pigment 10 to 200 nm, and the anthraquinone cyclic electron-rich N ^{( III )} , O ^{( II )} and also S ^{( II )} does not have the substituent of greenish yellow hue 1- or 2-phenylthio-substituted anthraquinone 99: 1 weight ratio of 10: 90, preferably 95: 5 to 30: 70 weight ratio, and even more preferably from 95: relates to a colorant composition comprising a weight ratio of 5 to 50: 50. These compositions are particularly useful in the patterned color filter. In some cases the exception of 1-or 2-phenylthio group SOR ₁₀ , SO ₂ R ₁₀ , SO ₃ R ₁₀ , SO ₂ NR ₁₁ R ₁₂ , CN, COR ₁₀ , COOR ₁₀ , or CONR ₁₁ R ₁₂ substitution by the group or anthraquinone SO ₂ NR ₁₁ R ₁₂ is substituted compounds by is also claimed. ; This invention also relates, R ₁ , R ₂ and R ₃ at least one of the SOR ₁₀ , SO ₂ R ₁₀ , SO ₃ R ₁₀ , SO ₂ NR ₁₁ R ₁₂ , CN or COR ₁₀ or or R ₇ , R ₈ and R ₉ at least one of SO ₂ NR ₁₁ R ₁₂ provided that, however, R ₃ is SO ₂ NH ₂ relates to the non-compound of formula III or IV ; & . Formula III & ; Formula IV ; anthraquinone, a color filter, a coloring composition, a photoresist composition
