Title
(EN) NOVEL RESIN-COATED METALLIC PIGMENT AND METALLIC COATING MATERIAL CONTAINING THE PIGMENT
(FR) NOUVEAU PIGMENT METALLIQUE ENDUIT DE RESINE ET MATIERE D'ENDUCTION METALLIQUE CONTENANT LE PIGMENT
Abstract
(EN)
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.
(FR)
Pigment métallique enduit de résine que l'on prépare en utilisant (A) au moins un composant sélectionné parmi des acides carboxyliques insaturés à polymérisation radicalaire, des mono- et diesters d'acide phosphorique et d'acide phosphonique possèdant chacun une double liaison à polymérisation radicalaire et des agents de couplage ayant chacun une double liaison à polymérisation radicalaire, (B) un monomère à trois ou plusieurs doubles liaisons à polymérisation radicalaire et (C) un déclencheur de polymérisation, selon un procédé qui consiste à: traiter un pigment métallique avec le composant (A), puis à former une couche de résine sur la surface du pigment par addition graduelle d'au moins un des composants (B) et (C) pour induire la polymérisation. Le pigment s'avère excellent en termes de résistance aux intempéries, résistance chimique, brillance et stabilité en stockage dans des matières d'enduction aqueuses et permet la formation d'un finissage métallique. L'invention comporte également une matière d'enduction métalllique contenant le pigment métallique enduit de résine.
