Title:
NOVEL RESIN-COATED METALLIC PIGMENT AND METALLIC COATING MATERIAL CONTAINING THE PIGMENT
Document Type and Number:
WIPO Patent Application WO/1996/038506
Kind Code:
A1
Abstract:
A resin-coated metallic pigment which is prepared by using (A) at least one member selected from among radical-polymerizable unsaturated carboxylic acids, mono- and di-esters of phosphoric acid and phosphonic acid each having a radical-polymerizable double bond and coupling agents each having a radical-polymerizable double bond, (B) a monomer having three or more radical-polymerizable double bonds and (C) a polymerization initiator according to a process characterised by treating a metallic pigment with the component (A) and thereafter forming a resin layer on the surface of the resulting pigment by gradually adding at least one of the components (B) and (C) to cause polymerization and which is excellent in weathering resistance, chemical resistance, gloss and storage stability in aqueous coating materials and permits the formation of a metallic finish; and a metallic coating material containing the resin-coated metallic pigment.
