Provided are: a nonaqueous dispersant which has excellent dispersibility and dispersion stability, and is capable of forming a resin layer that has excellent hydrolysis resistance; and a coloring material dispersion liquid and a colored resin composition, each of which uses the nonaqueous dispersant. A nonaqueous dispersant characterized by being a polymer which has at least a constituent unit represented by general formula (I) and wherein at least some of the nitrogen moieties of the constituent unit form a salt with an acidic organic phosphorus compound. This nonaqueous dispersant is also characterized in that: the acidic organic phosphorus compound contains one or more compounds that are selected from the group consisting of organic phosphonic acid monoester compounds obtained by adding a monofunctional epoxy compound or a monofunctional oxetane compound to an organic phosphonic acid. (In general formula (I), the symbols are as defined in the description.) Cette invention concerne : un dispersant non aqueux doué d'une excellente capacité de dispersion et stabilité de dispersion, et capable de former une couche de résine ayant une excellente résistance à l'hydrolyse ; et un liquide de dispersion de matière colorante et une composition de résine colorée, chacun d'entre eux utilisant ledit dispersant non aqueux. Le dispersant non aqueux selon l'invention est caractérisé en ce que c'est un polymère contenant au moins un motif constitutif représenté par la formule générale (I), une partie au moins des fragments azote du motif constitutif formant un sel avec un composé de phosphore organique acide. Ce dispersant non aqueux est également caractérisé en ce que : le composé de phosphore organique acide contient un ou plusieurs composés qui sont choisis dans le groupe constitué par les composés de type monoester d'acide phosphonique organique obtenus par ajout d'un composé d'époxy monofonctionnel ou d'un composé d'oxétane monofonctionnel à un acide phosphonique organique. (Dans la formule générale (I), les symboles sont tels que définis dans la description).
