<p>Disclosed is a metallic pigment composition which is stably dispersed in a water borne coating composition and which also provides with smooth coatings having superior water resistance. The metallic pigment composition comprises a metallic pigment and a phosphorus compound represented by the following formula (I) or (II); <CHEM> wherein l is 0 or 1, m is an integer of 1 to 4, R1 represents an aliphatic, alicyclic or aromatic hydrocarbon group which has a valence of m, R2, R7 and R8, the same or different, represent a hydrogen atom, a C1 - C24 aliphatic hydrocarbon group, a C3 - C24 alicyclic hydrocarbon group or a C6 - C24 aromatic hydrocarbon group, R3, R4, R5 and R6, the same or different, represent a C1 - C3 alphatic hydrocarbon group or a C6 or C7 aromatic hydrocarbon group, <CHEM> wherein n is 0, 1 or 2, p is an integer of 1 to 3, n + P equals 3, q is 0 or 1, R9, R14 and R15, the same or different, represent a hydrogen atom, a C1 - C24 aliphatic hydrocarbon group, a C3 - C24 alicyclic hydrocarbon group or a C6 - C24 aromatic hydrocarbon group, R10, R11, R12 and R13, the same or different, represent a C1 - C3 alphatic hydrocarbon group or a C6 or C7 aromatic hydrocarbon group; the phosphorus compound being present in an amount of 0.5 to 200 parts by weight based on 100 parts by weight of the metallic pigment. The present invention also provides a water borne coating composition which contains the metallic pigment composition.</p> |
