| abstract |
A dispersion composition according to the present invention contains: a material to be dispersed; a dispersion medium; and a polymer (P) which is at least one substance selected from the group consisting of polyamic acids, polyamic acid esters and polyimides, and which has a structural unit U1 derived from a diamine compound (D1) represented by formula (1) and a structural unit U2 derived from a diamine compound (D2) that is different from the diamine compound (D1). In the formula, in cases where n is 0, at least one of R1 to R4 moieties represents a monovalent group having an ionic functional group, and in cases where n is 1, at least one of R1 to R8 moieties represents a monovalent group having an ionic functional group. |
