<p>A water dispersible metallic pigment composition comprises a metallic pigment such as an aluminium pigment incorporated in an associated surfactant structure such as a micelle. The micelle is formed from surfactant concentrations above the critical micelle concentration. The surfactant system may be a binary system comprising surfactant and water or a ternary system including a co-surfactant. The surfactant strucrure is formed prior to the addition of the metallic pigment. The metallic pigment may include a milling aid such as mineral spirits and/or a lubricant such as stearic acid. The metallic pigment composition is easily dispersed and has improved dispersion and gassing stability. Various coating compositions incorporating the metallic pigment composition are described.</p> |
