Phthalocyanine pigments having 0-4 chlorine atoms have a narrow particle-size range with 90% of particles between about 0.01-0.10 &#x3bc;m, the average particle size of no more than about 0.5 &#x3bc;m, a D99 of no more than about 0.3 &#x3bc;m, and a polydispersity of about 2.0 or less. Pigment compositions contain the phthalocyanine pigment and water-based dispersing resin. The pigments and the compositions are compatible with waterborne coating systems, exhibit an excellent metallic down travel, and are especially useful for the automotive painting applications.
