PIGMENT CONCENTRATE

PROBLEM TO BE SOLVED: To provide a resin which is widely compatible with different binder systems and allows compositions of pigment concentrates having a low volatile organic content (VOC).SOLUTION: Non-aqueous pigment concentrate comprises one or more pigments, one or more dispersants, and at least one resin, and is characterized in that the resin is a polyester comprising at least one oligo-ester building block with a hydrophobic tail linked thereto, wherein the hydrophobic tail is selected from the group consisting of branched hydrocarbons, hydrocarbons containing a cyclic group, and linear hydrocarbons, provided that the linear hydrocarbon is linked to the oligo-ester building block via an ester group, the linear hydrocarbon contains 3 to 12 carbon atoms. 【課題】種々のバインダー系と広く相溶性であり、低い揮発性有機含量（VOC）を有する顔料濃厚物の組成物を可能にする樹脂の提供。【解決手段】１以上の顔料、１以上の分散剤及び少なくとも１の樹脂を含む非水性顔料濃厚物において、樹脂が、疎水性尾部を連結された少なくとも１のオリゴ−エステル構築ブロックを含むポリエステルであり、疎水性尾部が、分岐状炭化水素、環式基を含む炭化水素及び直鎖状炭化水素から選択され、但し、前記直鎖状炭化水素はエステル基を介してオリゴ−エステル構築ブロックに連結されておりかつ３〜１２の炭素原子を有する、顔料濃厚物。【選択図】なし
