Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pigment dispersing resin having excellent pigment dispersing property for improving usability of a printing ink or a coating material, a resin dispersing agent and a pigment composition containing it, and an acidic acrylic block resin used for a pigment dispersed body. SOLUTION: The acidic acrylic block resin contains a block (A) which substantially does not contain carboxylic acid groups and a block (B) which contains carboxylic acid groups. A block (B') having hydroxy groups is prepared by living polymerization of monomers containing monomers with hydroxy groups. The hydroxy groups of the block are then modified by a compound (c) that reacts with the hydroxy groups and generates carboxylic groups which exist after the reaction to obtain the block (B) containing carboxylic acid groups.
