Non-leafing aluminium flake pigment and method of making same.

摘要

A substantially non-leafing pigment is constituted of aluminium flake particles having a surface layer of a residue of a milling agent, of which a substantial proportion was a branched chain saturated fatty acid, usually iso-stearic acid. The aluminium flake pigment is produced in conventional manner either in the presence of the milling agent alone or in the presence of a milling agent vehicle such as mineral spirits. The milling agent may include a proportion of a conventional non-leafing milling agent such as oleic acid.
