摘要：
A photosensitive coloring composition for color filters using coloring compositons containd (A) a binder resin having an amido group and a carboxyl group and (B) a coloring material has excellent photosensitivity and has improved dispersibility upon producing in particular a coloring composition containing a black pigment such as a carbon black. Use of (A') an epoxy(meth)acrylate resin can further improve the photosensitivity and from a black matrix having sufficient film strenght and low reflectivity. Furhter, use of a modified carbon black treated with a compound having a isocyanate group and an ethylenically unsaturaged bond in a molecule as the coloring material can give rise to a photosensitive resin composition excellent in optically opaque property, photosensitivity and dispersion stability.
