POLYMER DISPERSANT FOR INORGANIC PIGMENT
PROBLEM TO BE SOLVED: To provide a polymer dispersant for an inorganic pigment capable of producing a ceramic sheet excellent in the dispersibility of the inorganic pigment and sheet strength.SOLUTION: A polymer dispersant for an inorganic pigment used in a nonaqueous solvent contains: a constitutional unit (a) derived from at least one kind of compound selected from among a dibasic acid, an anhydrous dibasic acid and a dibasic acid monoester having an ethylenic double bond; at least one kind of constitutional unit (b) selected from among polyether having an unsaturated group at a terminal; preferably, a constitutional unit (c) selected from among methyl (meth)acrylate, stearyl (meth)acrylate, branch stearyl (meth) acrylate, benzyl (meth)acrylate and styrene; and a copolymer having a mass ratio [(c)/(b)] of the constitutional unit (c) to the constitutional unit (b) of 0.05 or more and 7.5 or less.SELECTED DRAWING: None
【課題】無機顔料の分散性とシート強度に優れるセラミックシートを製造可能な無機顔料用高分子分散剤を提供する。【解決手段】エチレン性二重結合を有する、二塩基酸、無水二塩基酸及び二塩基酸モノエステルから選ばれる少なくとも１種の化合物由来の構成単位（ａ）、末端に不飽和基を有するポリエーテルから選ばれる少なくとも１種の構成単位（ｂ）、並びに好ましくはメチル（メタ）アクリレート、ステアリル（メタ）アクリレート、分岐ステアリル（メタ）アクリレート、ベンジル（メタ）アクリレート及びスチレンから選ばれる構成単位（ｃ）を含有し、構成単位（ｂ）に対する構成単位（ｃ）の質量比［（ｃ）／（ｂ）］が０．０５以上７．５以下である共重合体を含む、非水系溶媒中で用いる無機顔料用高分子分散剤。【選択図】なし
