Metal particles, e.g. aluminum, are treated with ionic organic phosphate, being thereby transformed to a state capable of resisting attack from an aqueous medium. The treated particles may be incorporated into a water-borne coating.

Water resistant aluminum particles and coating

In a composition of matter including a leafing, metallic pigment and a means for inhibiting reaction of the pigment to form hydrogen gas, the improvement including a liquid fatty acid in an amount effective for at least reducing loss of optical properties which would occur in the absence of such fatty acid. A water-borne coating containing an effective amount of liquid fatty acid for improved optical properties.
