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 recoatability in recoating dirtied coatings after due repair, as well as a method of forming a coating film and a multilayerd 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 the solid basisand (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 copolymerizable ethylenically unsaturated monomer.
