Title: PHOTOSENSITIVE COLORING COMPOSITION, BLACK MATRIX, COLORING SPACER, IMAGE DISPLAY DEVICE, AND PIGMENT DISPERSION
Abstract:
 The present invention addresses the problem of providing a photosensitive coloring composition having excellent light blocking performance while also having excellent dispersing properties and plate-making properties and exhibiting adequately low relative permittivity. This photosensitive coloring composition contains at least a colorant (A), a dispersant (B), an alkali-soluble resin (C), and a polymerization initiator (D). The colorant (A) includes an organic black pigment, which is the compound (A-1) represented by general formula (1), a geometric isomer of said compound, a salt of said compound, or a salt of a geometric isomer of said compound; and the dispersant (B) includes a polymer dispersant having as a functional group a quaternary ammonium salt group.
