Title (EN) ABA BLOCK COPOLYMER, DISPERSANT, AND PIGMENT DISPERSION COMPOSITION
(FR) COPOLYMÈRE SÉQUENCÉ ABA, AGENT DISPERSANT ET COMPOSITION DE DISPERSION DE PIGMENT
(JA) ABA型ブロック共重合体、分散剤及び顔料分散組成物
Abstract:
(EN) Provided is an ABA block copolymer which, when used as a pigment dispersant in an aqueous medium, is capable of yielding a pigment dispersion composition having superior dispersion stability. The ABA block copolymer contains an A block comprising a structural unit represented by general formula (1) and a structural unit derived from a vinyl monomer comprising an acidic group, and a B block comprising a structural unit derived from a vinyl monomer comprising an aromatic ring group or an alicyclic alkyl group, and has an acid value of 30–250 mg KOH/g (in general formula (1), R1 is a hydrogen atom or a methyl group, and R2 is an alkyl group comprising 2–10 carbon atoms).
(FR) L'invention concerne un copolymère séquencé ABA qui, lorsqu'il est utilisé comme dispersant de pigment dans un milieu aqueux, est capable de donner une composition de dispersion de pigment ayant une stabilité de dispersion supérieure. Le copolymère séquencé ABA contient un bloc A comprenant un motif structural représenté par la formule générale (1) et un motif structural dérivé d'un monomère vinylique comprenant un groupe acide, et un bloc B comprenant un motif structural dérivé d'un monomère vinylique comprenant un groupe cyclique aromatique ou un groupe alkyle alicyclique, et présente un indice d'acide de 30 à 250 mg KOH/g (dans la formule générale (1), R1 est un atome d'hydrogène ou un groupe méthyle et R2 est un groupe alkyle comprenant de 2 à 10 atomes de carbone).
(JA) 水性媒体中において顔料分散剤として用いたときに分散安定性が優れた顔料分散組成物を与えることができるABA型ブロック共重合体を提供する。 下記一般式(1)で表される構造単位及び酸性基を有するビニルモノマーに由来する構造単位を含有するAブロックと、芳香環基又は脂環族アルキル基を有するビニルモノマーに由来する構造単位を含有するBブロックとを有し、酸価が30~250mgKOH/gである、ABA型ブロック共重合体。 〔一般式(1)において、Rは水素原子又はメチル基である。Rは炭素数が2~10のアルキル基である。〕
