(57) [Summary] (Modified) [Objective] To provide a compound that effectively disperses a pigment in an aqueous coating composition. [Structure] A compound having a polymer skeleton, having a substituent that interacts with the pigment and a substituent that stabilizes, wherein the substituent that interacts with the pigment is Where A 1 -A 4 are OH, alkyl, alkoxy, alkoxyalkoxy, alkanoyloxy, or halogen, but A 1 , A 2 and A 3 must not all be alkyl. Substituents having a selected functional group and stabilizing structure (In the formula, D 1 and D 2 represent βOβ or βNA 5 β, A 5 is H or alkyl, and R 1 is a divalent group selected from straight chain or branched chain alkylene. Yes, R 2 is H or a mixture of H and alkyl, R 3 is alkyl, m is 0 to 1000, n is 1 to 100 0). |
