ALUMINIUM PIGMENT COMPOSITION

摘要

An aluminium pigment composition disclosed herein comprises aluminium flakes, a phosphorus supplied from an inorganic phosphoric acid in an amount of 500 to 10,000 ppm based on the aluminium weight, an aliphatic compound having at least one functional group within a molecule in an amount of 0.3 to 5 parts by weight per 100 parts by weight of aluminium, water in an amount of 0.05 to 10 parts by weight of aluminium, a water-compatible alcohol in an amount of 5 to 100 parts by weight per 100 parts by weight of aluminium and a hydrocarbon oil in an amount of 1 to 70 parts by weight of aluminium. The aluminium pigment composition according to the invention is particularly suitable for incorporating in the water base paint. 22
