Abstract:
A coating composition containing at least one component (a) selected from organosilanes, hydrolyzates of the organosilanes, and condensates of the organosilanes represented by Formula 1(R1)nSi(OR2)4- nâ€ƒâ€ƒ(1) (wherein, R1 is a monovalent organic group having 1 to 8 carbon atoms: when multiple R1s exist, they are either identical to or different from each other; R2 is an alkyl group having 1 to 5 carbon atoms or an acyl group having 1 to 6 carbon atoms: when multiple R2s exist, they are either identical to or different from each other; and n is an integer ranging from 0 to 2);and a polymer component (b) having a molecular weight Mw of at least 5000, and having a silyl group wherein silicon atoms are bonded with a hydrolytic group and/or a hydroxy group; wherein the component (b) comprises a substance selected from polymers having a structural unit (b-1) expressed by Formula 2â€ƒ(wherein, R3 to R5 are CmY2m+1, m is an integer independently ranging from 0 to 5, and Y is selected from F, H, and Cl separately) and/or a structural unit (b-2) expressed by Formula 3â€ƒ(wherein, Rf is an alkyl group or an alkoxyalkyl group having fluorine atoms and R3 to R5 have the same meaning as above).
