To provide a curable composition which has favorable insulating property and liquid repellency, and from which a cured film having liquid repellency capable of being sufficiently converted to be liquid-philic even by irradiation with ultraviolet light having a wavelength of at least 300 nm, can be formed, an article having a cured film obtained by curing the curable composition and its production process. A cured film is formed by using a curable composition comprising a liquid repellent polymer having units (u1) based on a liquid repellent compound represented by the following formula (m1):
wherein Cf is a C 1-20 fluoroalkyl group or a C 1-20 fluoroalkyl group having an etheric oxygen atom between carbon atoms,
each of R 1 and R 2 which are independent of each other, is a hydrogen atom, a C 1-6 alkyl group or a phenyl group,
X is an oxygen atom, a sulfur atom, a nitrogen atom or NH,
n in an integer of from 0 to 4,
m is 1 when X is an oxygen atom, a sulfur atom or NH, or 2 when X is a nitrogen atom,
Z is R 4 R 5 C=CR 3 -CO-, and
each of R 3 , R 4 and R 5 which are independent of one another, is a hydrogen atom or a methyl group. |
