Patent ID: 8222332

Claim:
A resin composition for forming a stable wrinkle patterned paint film comprising (A) a hydroxyl group containing acrylic resin comprising a hydroxyl group value of from 5 to 200 mgKOH/g and a number average molecular weight of from 500 to 20,000, (B) a hexakisalkyoxymethylated melamine resin, (C) a de-watering agent, (D) a blocked sulfonic acid compound having a blocking agent comprising a tertiary amine compound of boiling point from 50 to 300° C. where the mol ratio of the tertiary amine with respect to the sulfonic acid is from 0.2 to 0.9, (E) a silicate compound, and (F) at least one type of material selected from among (a) organic resin particles of average particle diameter not more than 40 μm, (b) inorganic glass particles of average particle diameter not more than 100 μm and (c) inorganic fibers of average length not more than 300 μm, further comprising a mass ratio of the (A) component and the (B) component as solid fractions that is from 60/40 to 90/10, and in which, per 100 parts by mass in total as the solid fractions of the (A) component and the (B) component, the amount of the (C) component included as solid fraction is from 0.1 to 10 parts by mass, the amount of the (D) component included as solid fraction is from 0.1 to 5 parts by mass, the amount of the (E) component included as solid fraction is from 0.5 to 10 parts by mass and the amount of the (F) component included as solid fraction is from 1 to 30 parts by mass; wherein the resin composition, diluted with solvent, is capable of forming a paint film that has a stable wrinkle pattern after painting and baking.
