Abstract
Abstract An aluminium pigment composition suitable for incorporating in a water based paint comprises: (i) aluminium flakes; (ii) phosphorus supplied from an inorganic oxo acid of phosphorus in an amount of from 500 to l0,000 ppm based on the weight of the aluminium; (iii) an aliphatic compound having at least one functional group within the molecule, the aliphatic compound being present in an amount of from 0.3 to 5 parts by weight per l00 parts by weight of the aluminium; (iv) water in an amount of from 0.05 to l0 parts by weight of the aluminium; (v) a water-compatible alcohol in an amount of from 5 to l00 parts by weight of the aluminium; and (vi) a hydrocarbon oil in an amount of from l to 70 parts by weight of the aluminium.
