Claims18
A composition, comprising
- (A) water,
- (B) electroconductive nanoobjects,
- said electroconductive nanoobjects (B) having two external dimensions in the range of from 1 nm to 100 nm and a third external dimension in the range of from 1 μm to 100 μm,
- wherein a weight fraction of said electroconductive nanoobjects (B) is in the range of from 0.01 wt.-% to 1 wt.-% based on a total weight of the composition, and
- (C) one or more styrene/(meth)acrylic copolymers dissolved in water,
- wherein said dissolved copolymers (C) each has a number average molecular weight in the range of from 500 g/mol to 22000 g/mol, and
- a total weight fraction of said dissolved copolymers (C) is in the range of from 0.02 wt.-% to 5 wt.-%, based on the total weight of the composition.
