Document Type and Number:
Japanese Patent JP5206970
Kind Code:
B2
Abstract:
A powder is hydrophilized by treating surfaces of particles with a hydrolyzable silyl group-containing acid anhydride compound, dispersing the surface treated particles in water, adding a base, and heating the dispersion for thereby hydrolyzing the acid anhydride moiety to open its ring and neutralizing the resultant carboxylic acid with the base. The hydrophilized powder is fully dispersible in aqueous media.
