Title:
COATED PLATE-LIKE TITANIC ACID PARTICLES, METHOD FOR PRODUCING SAME AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2023/054664
Kind Code:
A1
Abstract:
The present invention provides: coated plate-like titanic acid particles which are capable of forming a designed coating film that exhibits high adhesion and water resistance, while having a good silky texture and a good shaded appearance in either case where the coated plate-like titanic acid particles are added to a water-based coating material or where the coated plate-like titanic acid particles are added to an organic solvent-based coating material; and a method for producing the coated plate-like titanic acid particles. According to the present invention, the surfaces of plate-like titanic acid particles are provided with: an oxide and/or hydroxide of aluminum; and at least one substance that is selected from among a silane coupling agent, a hydrolysis product thereof, and a condensate of the silane coupling agent or the hydrolysis product. A silane coupling agent is mixed with the plate-like titanic acid particles, which have an oxide and/or hydroxide of aluminum on the particle surfaces, in a solvent and the resulting mixture is subsequently dried, thereby producing the coated plate-like titanic acid particles of the present invention.
