Abstract:
1. A coating comprising: a coating component comprising a polymer consisting of 10 parts by mass or less of a polymer block (A) having a repetitive unit of dimethyl siloxane, a polymer block (B) having a repetitive unit of radical polymerizable monomers, and 1 to 20 parts by mass of a silicon-containing graft-linking unit (C) which is copolymerized to polymer block (A) and polymer block (B), the total amount of polymer blocks (A), (B) and (C) is 100 parts by mass; at least one kind of an anionic surfactant comprising a sulfate salt of polyoxyalkylene aryl ether, a sulfate salt of polyoxyalkylene alkylaryl ether, a formalin condensate of a sulfate salt of polyoxyalkylene aryl ether, or a formalin condensate of a sulfate salt of polyoxyalkylene alkylaryl ether, or mixtures thereof; a nonionic surfactant having the number of the repetitive unit of polyoxyethylene of 10 or more; and colloidal silica having an average particle size of 60 nm or less, wherein the colloidal silica is 0.5 to 20 parts by mass in solid form for 100 parts by mass of the polymer, and an area of the colloidal silica exposed at a coating surface occupies 70% or more of the coating surface.
