Title:
RESIN-COATED METALLIC PIGMENT
Document Type and Number:
WIPO Patent Application WO/2020/021735
Kind Code:
A1
Abstract:
Aluminum pigments not having undergone any surface treatment are high in metallic sensation and appearance attractiveness, but have a drawback in that coating materials or printing inks containing such aluminum pigment give coating films in which adhesion between the aluminum pigment and the resin is low and from which a large amount of aluminum pigment particles separate in an adhesion test based on peeling with cellophane adhesive tape. Thus, the coating films are insufficient in satisfying the adhesion properties required of printed matter produced with inks containing metallic pigments. It was found that a resin-coated metallic pigment having a very small average particle diameter gave a coating material which gave coating films wherein the smaller the number of specific particles contained therein, the higher the adhesion. The resin-coated metallic pigment of the present invention has been thus completed.
