ABSTRACT:
A process for preparing a copper powder for electroconductive paints, which comprises adding to a dispersion bath of copper powder and a dispersion medium a mixture of a titanium acylate polymer and a higher carboxylic acid ester to form a film of the titanium acylate polymer and the higher carboxylic acid ester on the surfaces of the particles of said copper powder, and if necessary, removing the dispersion medium to obtain the copper powder for electroconductive paints. The copper powder thus obtained is coated on the surfaces of its particles with the titanium acylate polymer and the higher carboxylic acid ester.
