POLYMER DISPERSANT FOR INORGANIC PIGMENT
PROBLEM TO BE SOLVED: To provide a polymer dispersant for inorganic pigment capable of improving a sheet strength of a ceramic sheet while securing good dispersibility of an inorganic pigment.SOLUTION: A polymer dispersant for inorganic pigment used in a nonaqueous solvent contains a copolymer containing one constitutional unit (a) derived from at least one compound selected from monobasic acid, dibasic acid, anhydrous dibasic acid and dibasic acid monoester and at least one constitutional unit (b) selected from a constitutional unit represented by -[-C(R)(R)-C(R)((C=O)X-[-RO-]-R)-]- and a constitutional unit derived from a compound represented by RO(AO)R, and at least one defoaming agent selected from an olefinic defoaming agent, a silicone defoaming agent and an acrylic defoaming agent.SELECTED DRAWING: None
【課題】無機顔料の良好な分散性を確保しつつ、セラミックシートのシート強度を向上可能な無機顔料用高分子分散剤の提供。【解決手段】一塩基酸、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）、並びに、−［−Ｃ（Ｒ１）（Ｒ２）−Ｃ（Ｒ３）（（Ｃ＝Ｏ）Ｘ１−［−Ｒ４Ｏ−］ｎ−Ｒ５）−］−で表される構成単位及びＲ11Ｏ(ＡＯ)mＲ12で表される化合物由来の構成単位から選ばれる少なくとも１つの構成単位（ｂ）を含有する共重合体と、オレフィン系脱泡剤、シリコーン系脱泡剤及びアクリル系脱泡剤から選ばれる少なくとも１種の脱泡剤と、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
