The present specification provides a compound represented by Chemical Formula 1, a colorant composition, a resin composition, a photosensitive material, a color filter and a display device comprising the same.

Xanthene-based compound and photosensitive resin composition comprising same

The present specification relates to a method for preparing a colorant composition comprising dissolving a first xanthene-based dye having the same number of positive charges and negative charges and a second xanthene-based dye having more negative charges than positive charges by one or more in a first solvent; and precipitating the dissolved first xanthene-based dye and the dissolved second xanthene-based dye in a second solvent, and a colorant composition, a colorant dispersion, a photosensitive resin composition, a color filter and a liquid crystal display device.

Method for producing colorant composition, and colorant composition, colorant dispersion, photosensitive resin composition, color filter, liquid crystal display device produced using same

Disclosed is a photosensitive resin composition suitable for use in a transflective liquid crystal display (LCD). The photosensitive resin composition uses, as an alkali-soluble binder resin, a blend of two kinds of binder resins. The first binder resin has a weight average molecular weight greater than or equal to 1,000 but lower than 20,000 and contains no reactive group. The second binder resin has a weight average molecular weight greater than or equal to 20,000 but lower than 80,000 and contains reactive groups. The photosensitive resin composition has good adhesion to an underlying substrate while forming a high resolution fine pattern.
