Japanese Patent JP3741470

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain the subject composition containing specific aluminum powder, and a phosphorus compound, water and/or a hydrophilic solvent as essential components, excellent in dispersibility and storage stability, and suitable for aqueous metallic inks, etc. SOLUTION: This new aqueous aluminum pigment composition is obtained by grinding (A) atomized aluminum powder and/or aluminum foils in (B) a hydrophobic inactive solvent, treating the obtained flaky aluminum powder with an unsaturated carboxylic acid, removing the component B, and subsequently treating the left treated aluminum powder with (C) a phosphorus compound, and water and/or (D) a hydrophilic solvent. The component C is preferably one or more kinds of compounds selected from phosphoric ester compounds of the formula [R is H, a 8-24C alkyl, an alkenylene, etc.; A is a 2-4C alkylene; (m) is 0-20; R1 is H, an alkyl, an alkenyl, etc.; (n) is 1-10], such as tridecyl acid phosphate.
