A composition comprising a surfactant, a surfactant, a fluorine-containing compounds and their uses

摘要

Surface modifier for imparting soil resistance or surfactants excellent polymer containing a structural unit derived from the compound represented by the following formula (a), the reduction ability of the surface tension and application as a coating, provision of the composition at each use them. Furthermore, provision of useful novel fluorine-containing compound as a surface-active agent, even of the above compounds. CH ^₂ = CR ¹ -COX-CR ₂ R ³ - (CH _{2) n} -COO-Q ¹ -Rf ¹ (a) Wherein, X: -; -NR ⁴ or -O- ¹ R:; hydrogen atom or a methyl group, and ⁴ R ^2, R ³ R: independently of one another, or a hydrogen atom, an alkyl group having 1 to 3 carbon atoms a group represented by (r) formula, - _m (CH ^₂₎ m -COO-Q ₂ -Rf ₂ and (r) n: independently of one another, an integer from 0 to 4; Independently of one another, polyfluoroether group or a polyfluoroalkyl group having a carbon number 1~6; ² Q and Q ^{1:: 2} Rf and Rf ¹ are independently of one another, a single bond or a divalent linking group.
