Abstract:
A dispersant for preparing a dispersion of color pigments, a dispersion of color pigments including the dispersant, and a photosensitive resist including the dispersion of color pigments are disclosed. The dispersant is an amine-based dispersant including a photo-crosslinkable or photo-dimerizable group containing an anhydride functional group. The dispersant improves the developing property of photosensitive resists.
