Abstract
PURPOSE: To provide a title dispersant capable of advantageously dispersing carbon black into an aqueous medium in high concentration and low viscosity by use of a small quantity without using a specific means, which consists of an organic polymer contg. specific amounts of combined specific repeating units and ionizing groups.
CONSTITUTION: A vinyl monomer having 6π-electron aromatic ring, such as styrene and a (meth)acrylate ester is copolymerized with a vinyl monomer or cpd. having ionizing group, such as sodium p-styrenesulfonate or 2-acrylamido-2-methylpropanesulfonic acid. This provides a dispersant consisting of a water-soluble organic polymer with MW of 500W40,000, having the combined ionizing group of 0.5mmol/g or more, and consisting of a single repeating unit contg. combined 6π-electron aromatic ring or 3mol% of the above repeating unit and the balance of at least one other repeating unit. Using this dispersant in 0.5W25wt% allows carbon black to be easily dispersed into water or an aqueous inorganic solution.
