Zusammenfassung:	To provide a dispersion excellent both in dispersion stability and drying resistance of a dispersoid and to provide a dispersant-containing liquid which can be suitably used for the preparation of the dispersion.SOLUTION: There is provided a dispersion containing a polyester as a dispersant, water, a dispersoid and a solvent, wherein the polyester has a carboxyl group and a sulfo group which do not constitute an ester bond and the solvent contains a polyol having a log P of -2.0 or more and 0.0 or less. The ratio of the content of a monomer having a carboxyl group to the content of a monomer having a sulfo group in the polyester is preferably 50% or more and 200% or less in a molar ratio.SELECTED DRAWING: None 【課題】分散質の分散安定性および耐乾燥性のいずれにも優れた分散液を提供すること、また、前記分散液の調製に好適に用いることができる分散剤含有液を提供すること。【解決手段】本発明の分散液は、分散剤としてのポリエステルと、水と、分散質と、溶剤とを含み、前記ポリエステルは、エステル結合を構成しないカルボキシル基およびスルホ基を有するものであり、前記溶剤は、ｌｏｇＰが－２．０以上０．０以下であるポリオールを含むものである。前記ポリエステル中における、前記スルホ基を有するモノマーの含有量に対する前記カルボキシル基を有するモノマーの含有量の比率は、モル比で、５０％以上２００％以下であることが好ましい。【選択図】なし
