Abstract:
(EN) The present invention addresses the problem of providing an aqueous pigment dispersion which can maintain superior dispersibility and long-term storage stability, and can be used for producing printed matter having superior color development when printed on plain paper. The present invention pertains to an aqueous pigment dispersion which contains a pigment including C.I. pigment red 150, a water-soluble organic solvent, and a radical polymer having an aromatic cyclic structure or a heterocyclic structure and an acid value of 50-120 mgKOH/g, and which is characterized in that all or a portion of acid radicals included in the radical polymer are neutralized by a basic compound, and the mass ratio of the radical polymer to the pigment is within the range of 0.001-0.1.
(FR) La présente invention aborde le problème de la fourniture d'une dispersion aqueuse de pigment qui peut maintenir une dispersibilité supérieure et une stabilité de stockage à long terme, et peut être utilisée pour produire une matière imprimée ayant un développement de couleur supérieur lorsqu'elle est imprimée sur un papier ordinaire. La présente invention concerne une dispersion aqueuse de pigment qui contient un pigment comprenant le pigment rouge C.I. 150, un solvant organique soluble dans l'eau, et un polymère radicalaire ayant une structure cyclique aromatique ou une structure hétérocyclique et un indice d'acide de 50 à 120 mg de KOH/g, et qui est caractérisée en ce que tout ou partie des radicaux acides inclus dans le polymère radicalaire sont neutralisés par un composé basique, et le rapport pondéral du polymère radicalaire au pigment se situe dans la plage de 0 001 à 0,1.
(JA) 本発明が解決しようとする課題は、優れた分散性および長期間の保存安定性を維持でき、かつ、普通紙に印刷した場合に発色性に優れた印刷物の製造に使用可能な水性顔料分散体を提供することである。本発明は、C.I.ピグメントレッド150を含む顔料、水溶性有機溶剤、及び、芳香族環式構造または複素環式構造を有する酸価50~120mgKOH/gのラジカル重合体を含有する水性顔料分散体であって、前記ラジカル重合体が有する酸基の一部または全部は塩基性化合物によって中和されており、前記顔料に対する前記ラジカル重合体の質量比率が0.001~0.1の範囲であることを特徴とする水性顔料分散体に関するものである。
