Abstract:
Provided is a coating composition containing a silicon atom-containing resin. The resin includes a constituent unit (A) derived from a monomer (a) having at least one kind of silicon atom-containing group selected from the group consisting of groups represented by formulae (I), (II), (III), and (IV), a constituent unit (B) derived from a monomer (b) which is a (meth)acrylic acid ester represented by a formula (b), and a constituent unit (C) derived from a monomer (c) other than the monomers (a) and (b). The monomer (a) has a molecular weight of greater than 2500. A content of the constituent unit (A) is greater than 20% by mass in all constituent units. The monomer (c) has a homopolymer solubility parameter SP of less than or equal to 9.5 and has no cyclic structure. A content of the unit (C) is greater than 2% by mass in all constituent units.
