Abstract

Abstract 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 phosphorous compound represented by the following formula (I) or (II); ##STR1## wherein l and 0 or 1, m is an integer of 1 to 4, R 1 , R 2 R 7 and R 8 represent aliphatic, alicyclic or aromatic hydrocarbon groups which are the same or different, selected from a hydrogen atom, a C 1 -C 24 aliphatic hydrocarbon group, a C 3 -C 24 alicyclic hydrocarbon group or a C 6 -C 24 aromatic hydrocarbon group, and R 1 has a valence of m, R 3 , R 4 , R 5 and R 6 , which are the same or different, represent C 1 -C 3 aliphatic hydrocarbon group or a C 6 or C 7 aromatic hydrocarbon group, ##STR2## wherein n is 0, 1 or 2, p is an integer of 1 to 3, n+P equals 3, q is 0 or 1, R 9 , R 14 and R 15 , which are the same or different, represent a hydrogen atom, a C 1 -C 24 aliphatic hydrocarbon group, a C 3 -C 24 alicyclic hydrocarbon group or a C 6 -C 24 aromatic hydrocarbon group, R 10 , R 11 , R 12 and R 13 , which are the same or different, represent a C 1 -C 3 aliphatic hydrocarbon group or a C 6 or C 7 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.
