Abstract
A coated film and a coated glass improved in the resistance to fouling derived from water and oil repellency, and in the durability, the abrasion resistance, and the exfoliation of stacked outer layer, are provided by a specific coating composition having at least one component (a) selected from organosilanes, hydrolyzates of the organosilanes, and condensates of the organosilanes, and component (b) containing a silyl group wherein one of silicon atoms bonded with a hydrolytic group and/or a hydroxy group.
Claims15
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- n (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 2
- (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 3
- (wherein, Rf is an alkyl group or an alkoxyalkyl group having fluorine atoms and R3 to R5 have the same meaning as above).
