Abstract
A dry clay product useful as a filler in organic solvent-based paints and water-based paints to impart improved gloss to dried films of the paints and in paper coatings to improve the gloss of paint films and paper coatings and to improve gloss ink holdout in paper coatings and comprising a mixture of a major amount of kaolin clay particles and a minor amount of a nonionic surfactant compatible with water and oil and having an HLB value in the range of 3 to 15. Methods of making the novel clay product and coating materials including paints and paper coatings containing same.
