Document Type and Number:
WIPO Patent Application WO/2022/065490
Kind Code:
A1
Abstract:
Provided is a photosensitive coloring composition that causes little roughness of the surface of an electrode following a heat treatment. This photosensitive coloring composition is characterized: by containing (a) a coloring agent, (b) an alkali-soluble resin, (c) a photopolymerization initiator, (d) an ethylenically unsaturated compound, (e) a solvent and (f) a dispersing agent; in that the coloring agent (a) contains a compound represented by a specific general formula (I), a geometric isomer of the compound, a salt of the compound or a salt of a geometric isomer of the compound; in that the dispersing agent (f) contains an acrylic copolymer (f1) which contains repeating units represented by specific general formulae (1), (2) and (3) and does not contain a repeating unit having a quaternary ammonium group; and in that the content of chlorine atoms in the photosensitive coloring composition is 0.05 mass% or less relative to the total solids content in the photosensitive coloring composition.
