The present invention provides a colored coating composition and coating film-forming method that are capable of forming a multilayer coating film having excellent appearance with excellent smoothness, high flip-flop effect, and little metallic mottling.
The colored coating composition comprises:
(A) a hydroxy-containing resin,
(B) a curing agent,
(C) a diester compound represented by Formula (1)
wherein R1 and R2 are each independently a C4-18 hydrocarbon group, R3 is a C2-4 alkylene group, m is an integer of 3 to 25, and m oxyalkylene units (R3—O) may be the same or different,
(D1) a coloring pigment, and
(D2) an extender pigment;
- the total amount of the coloring pigment (D1) and the extender pigment (D2) being 40 to 180 parts by mass per 100 parts by mass of the hydroxy-containing resin (A) and the curing agent (B) in total.
