颜料分散浆料及电泳涂料
摘要：
本发明的目的在于提供一种可使涂装设备节能及节省设备的颜料的再分散性优良的颜料分散浆料及电泳涂料。具体而言，本发明涉及一种电泳涂料用颜料分散浆料，其含有颜料分散用树脂(A)、着色颜料(B)、体质颜料(C)及纤维素复合体(D)，其特征在于，相对于该树脂(A)的固体成分总量100质量份，含有：(1)60～800质量份作为着色颜料(B)的(b1)在成为基体的二氧化钛100质量份上以0.1～10.0质量份包覆Al2O3且不用SiO2包覆的二氧化钛、和/或(b2)氧化铁；(2)2～200质量份作为体质颜料(C)的一次粒子的平均粒径为0.01～0.1μm的微粒硫酸钡；以及(3)1～50质量份纤维素复合体(D)。
摘要（英）：

The purpose of the invention is to provide a pigment dispersing paste capable of saving energy of coating apparatus and saving redispersibility of dye of the apparatus and electrophoretic paint. Specifically, the invention relates to a pigment dispersing paste for electrophoretic paint, containing pigment dispersing resin (A), tinting color (B), color filler (C) and cellulose composition (D); responding to the solid component 100 weight parts of the resin (A), the paste is characterized by containing: (1) 60 to 800 weight parts of (b1) titanium dioxide coated by 0.1 to 10.0 weight parts of Al2O3 without SiO2 on 100 weight parts of titanium dioxide as matrix; and/or (b2) ferric oxide as the of tinting color (B); (2) 2 to 200 weight parts of micro barium sulfate with the mean grain size of linear particle being 0.01 to 0.1 micron as the color filler (C); and (3) 1 to 50 weight parts of cellulose composition (D).
