Surface treatment composition, process for producing the same, and surface-treated article

摘要

A surface treatment composition comprising (i) an organosilicon compound having an alkoxysilane functional group at the end of a fluorocontaining polyether chain and (ii) fluorocontaining polyether compound s, wherein a content of the fluorocontaining polyether compounds in the surface treatment composition is less than 25 mol % based on the surface treatment composition.

1. A surface treatment composition comprising an organosilicon compound represented by the general formula (A):
F—(CF2)q—(OC3F6)m—(OC2F4)n—(OCF2)o—(CH2)p—X—(CH2)r—C3H6—Si(X′)3-a(R1)a  (A) wherein q is an integer from 1 to 3; m, n, and o are independently integers from 0 to 200; p is 1 or 2; X is oxygen or a bivalent organic group; r is an integer from 0 to 17; R1 is a C1-22 linear or branched hydrocarbon group that does not have an unsaturated aliphatic bond; a is an integer from 0 to 2; and X′ is hydrolysable group, wherein a total content of fluorine-containing compounds represented by the general formulas (B) and (C) in the surface treatment composition is less than 25 mol % based on the surface treatment composition, and wherein a content of the fluorine-containing compound represented by general formula (C) is at least 0.1 mol % based upon the surface treatment composition:
F—(CF2)q—(OC3F6)m—(OC2F4)n—(OCF2)o—F  (B) wherein q, m, n and o are the same as described above,
F—(CF2)q—(OC3F6)m—(OC2F4)n—(OCF2)o—(CH2)p—X—(CH2)r—CH═CHCH3  (C) wherein q, m, n, o, p, r and X are the same as described above.
