Abstract:
Disclosed is a non-aqueous dispersant which is excellent in dispersibility and dispersion stability and able to form a resin layer with excellent hydrolysis resistance; a color material dispersion liquid containing the non-aqueous dispersant; and a color resin composition containing the non-aqueous dispersant. The non-aqueous dispersant is a polymer comprising at least one constitutional unit represented by the following general formula (I), wherein at least part of nitrogen sites of the constitutional units each form a salt with an acidic organophosphorous compound comprising one or more selected from the group consisting of organic phosphonic acid monoester compounds resulting from addition of a monofunctional epoxy compound or monofunctional oxetane compound to an organic phosphonic acid:
