NOVEL COLORANT COMPOUND AND METHOD OF MANUFACTURING THE SAME AS WELL AS BLUE RESIST COMPOSITION FOR USE IN COLOR FILTER CONTAINING THE SAME

摘要

The present invention provides (I) a method of manufacturing a triphenylmethane colorant that can suppress the sub-reactions in conversion to a sulfonamide and is industrially advantageous, (II) a colorant compound that has both excellent spectral characteristics and a high solubility relative to organic solvents or polymers as a coloring agent to be used in color filters and (III) a blue resist composition for use in a color filter that shows a high lightness and an excellent hue particularly for blue color and can be used to display an image that is excellent in terms of spectral characteristics and contrast. There are provided a method of manufacturing a sulfonylhalide by halogenating the sulfonic acid group in the colorant compound and a method of manufacturing a sulfonamide compound represented by the general formula (1) comprising conducting condensation reaction of the sulfonylhalide compound and an amine. There is also provided a blue resist composition for use in a color filter comprising at least one colorant compound according to the invention. general formula (1)
