A coating composition which comprises (A) a binder ingredient, (B) a first viscosity modifier, and (C) a second viscosity modifier, wherein the first viscosity modifier (B) comprises a product of reaction among (b1) a polyisocyanate compound, (b2) a primary monoamine having a number-average molecular weight of 300 or less, and (b3) a polyetheramine having a number-average molecular weight higher than 300 but less than 6,000, the proportion of the polyetheramine (b3) having a number-average molecular weight higher than 300 but less than 6,000 being 0.5 mass% or higher but less than 10 mass% with respect to the sum of the ingredients (b1) to (b3), and the second viscosity modifier (C) comprises a product of reaction among (c1) a polyisocyanate compound, (c2) a primary monoamine having a number-average molecular weight of 300 or less, and (c3) a polyetheramine having two or more amino groups and having a number-average molecular weight of 1,000 or higher but less than 6,000, the proportion of the polyetheramine (c3) having two or more amino groups and having a number-average molecular weight of 1,000 or higher but less than 6,000 being in the range of 10-30 mass% with respect to the sum of the ingredients (c1) to (c3). |
