(57) [Summary]nPROBLEM TO BE SOLVED: To improve dispersibility and dispersion stability of a pigment. Pigment dispersant capable of excelling in photosensitivity A coloring composition is provided.nThe weight average molecular weight represented by Chemical Formula 1 is 2 Pigment containing at least one compound of 000 to 30,000 The above problem is solved by a dispersant. Photosensitive resin composition The product is an alkali-soluble binder and a photopolymerizable monomer. , A photopolymerization initiator, a pigment, and the above-described pigment dispersant. Thus, the above-mentioned problem is solved. (Chemical formula 1 A represents a polymer part. X is C p H 2p Or SC p H 2p And p is an integer of 0 to 4. Y is -NHCO -Q-, -CONH-Q-, -COO-Q-, or- OCO-Q-, wherein Q is a hydrocarbon-based aromatic compound or Represents a heterocyclic compound, and m is 0 or 1. Z is -SO Three H or -O · SO Three H, and n is 1 to 4 It is an integer. )nEmbedded image |
