Beschreibung
Zusammenfassung:	An object of the present invention is to provide a living radical polymer that has a low molecular weight distribution and has a specific functional group at least at one end, and a resin-coated pigment that has high dispersibility of a resin composition comprising the living radical polymer, is excellent in properties such as preservation stability, discharge stability, and color developability in a dispersed state, and is suitably used in a pigment dispersion. The object mentioned above has been attained by the following: a living radical polymer having a specific functional group structure, the living radical polymer comprising a polymerization initiator-derived specific organic compound moiety at one end or in a backbone of the living radical polymer and being obtained by reacting a radical generator having a specific functional group with at least any end, for example, an iodine end ascribable to a precursor; a living radical polymer composition comprising the same; a resin-coated pigment obtained by coating with the living radical polymer composition; and a method for producing the living radical polymer having a specific functional group structure.
