Abstract:
A coating composition is formed from an acid-set coating varnish and a pigment composition. The pigment composition includes a specific organic dyestuff derivative and a specific basic-group-containing resin-type pigment dispersant. The coating composition excels in pigment dispersibility, nonflocculation properties, noncrystallizability and fluidity. When used as a coating, the coating composition has excellent color tone, gloss, hardness, weather resistance, and solvent resistance.
