Abstract: It is an object of the invention to provide a clear coating composition, which can give coating films showing good water repellency, in other words a factor giving a care-free and deluxe feeling to car owners, and which are excellent in non-sanding recoating dirtied coatings after due repair, as well as a method of forming a coating film and a multilayered coating film. The invention provides a clear coating composition which comprises (A) 100 parts by mass of the sum of a crosslinkable coating film-forming resin and a crosslinking agent on a solid basis and (B) 0.01 to 2 parts by mass of a ladder silicone copolymer obtainable by copolymerizing (b-1) a (meth)acryloxyalkyl-containing ladder silicone oligomer, (b-2) a crosslinkable functional group-containing ethylenically unsaturated monomer and optionally (b-3) another ethylenically unsaturated monomer.

Abstract: A top coat for an outer panel of an automotive vehicle includes a clear paint formed on a base coat paint. The clear paint is constituted of acrylic resin (A) having at least one ester group containing a silicone group and at least two epoxy groups in a molecule, acrylic resin (B) having at least two epoxy groups in a molecule, and acid cross-linking agent (C) having at least two chemically blocked carboxyl groups in a molecule. The base coat paint is constituted of acrylic resin (D) having at least two hydroxyl groups in a molecule, acrylic resin (E) having at least two hydroxyl groups and at least two epoxy groups in a molecule, and melamine resin (F) having a functional group capable of reacting with a hydroxyl group.

Abstract: This invention provides a clear paint composition suitable for application on base coated surface of a coating object, which is characterized by comprising (a) a hydroxyl- and epoxy-containing acrylic resin, (b) a high acid value polyester resin having an acid value of 120-200 mgKOH/g and a number-average molecular weight of 500-4,000, (c) an alkoxysilyl-containing acrylic resin, and (d) an acrylic resin containing alkoxysilyl groups and dimethylpolysiloxane side chains, and forming a coating which, after being cured, has a glass transition point within a range of 100-120° C.
