The present invention addresses the problem of providing: a dispersant which enables the production of a dispersed material having excellent dispersibility and storage stability even when the dispersant is used in a small amount; a dispersed material having excellent dispersibility and storage stability; an electrode film having excellent adhesiveness and electrical conductivity; and a non-aqueous electrolyte secondary battery having excellent rate properties and cycle properties. The problem can be solved by a dispersant which is a polymer containing 40 to 100% by mass of a (meth)acrylonitrile-derived unit and having a weight average molecular weight of 5,000 to 400,000.

A method is designed to prepare foamed, opacifying elements each having a target light blocking value (LBV.sub.T) of at least 3, using a textile fabric substrate with a light blocking value (LBV.sub.S). The LBV.sub.T-S difference is calculated; a foamable aqueous composition is chosen; a dry coating weight for the foamable aqueous composition (when foamed) is determined to form a single dry opacifying layer that is foamed, dried, and densified to provide a dry thickness at least 20% less than the original dry thickness. The single dry opacifying layer a has light blocking value that is equal to LBV.sub.T-S, ±15%. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBV.sub.T with the noted textile fabric substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.
