Zusammenfassung:	NOVEL COPOLYMER The present invention provides a novel copolymer useful as a dispersing agent for a pigment or the like. The novel copolymer contains a block chain (A) consisting of a polymer comprising at least one repeating unit selected from the group consisting of a repeating unit having a tertiary amino group and a repeating unit having a quaternary ammonium base; and a block chain (B) consisting of a copolymer comprising a repeating unit having a polyoxyalkylene chain and a repeating unit having an acidic group. The at least one repeating unit selected from the group consisting of a repeating unit having a tertiary amino group and a repeating unit having a quaternary ammonium base is, for example, a repeating unit represented by the following formula (II), and the repeating unit having a polyoxyalkylene chain is, for example, a repeating unit represented by the following formula (III):
