Phosphonic acid derivative treatment of metallic flakes

摘要

Metal pigment particles are treated with a product resulting from the reaction between an organic phosphonic acid with an amine having at least one organic group containing at least six carbon atoms to inhibit their reactivity to water. The treated metal particles can be used in coating and ink compositions. Additionally, the treated metal particles can be used to formulate pastes and dispersions that are provided to a coatings manufacturer.
