Abstract

PURPOSE: To obtain a powder metal pigment composition having excellent chemical resistance and excellent weather resistance by the procedure in which an aqueous alkali silicate solution is reacted with a specific organic compound to form silica sol and the silica sol is deposited on the surfaces of metal pigment particles.
CONSTITUTION: In an aqueous slurry of a powder metal pigment, an aqueous alkali silicate solution is reacted with an organic compound so as to form silica sol and then deposit it on the surfaces of the powder metal pigment particles in order to obtain a powder metal pigment composition. The powder metal pigment used includes pure silver, zinc, copper, and copper-zinc alloy in particular, and the pigment is dispersed into water alkalinized with ethanolamine, etc., to form a slurry. The preferred aqueous alkali silicate solution is the one of an SiO2/M2O (M is Na or K) raio of 2W4, and the organic compound used includes compounds containing active ions enough to convert alkali silicates into silicic acid and to polymerize its silanol groups to form siloxane bonds, e.g., carboxylic acid, etc.
