Abstract
Abstract An aluminum flake pigment composition for paint, containing 100 parts by weight of aluminum flake particles, 1 to 7 parts by weight of dimer acid, 0.5 to 14 parts by weight of aliphatic amine and other additives known in this art. The incorporation of the dimer acid enhances the color purity, metallic luster and anticorrosion property of a metallic paint containing the same composition and the incorporation of the aliphatic amine prevents the agglomeration of the aluminum flake pigment particles in the same composition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
76 words
An aluminum flake pigment composition for paint, consisting essentially of 100 parts by weight of aluminum flake particles, 1 to 7 parts by weight of dimer acid as an agent for enhancing the colour purity, metallic luster and anticorrosion property of the paint containing the same aluminum flake pigment composition, and 0.5 to 14 parts by weight of an aliphatic amine as an agent for preventing the agglomeration of aluminum flake particles in the same composition.
Claim 2
Dependent Claim
