To provide a water/oil repellent composition which can produce an article which has favorable water/oil repellency and washing durability, into which infiltration of a coating liquid to form a moisture-permeable waterproofing film or the like can be suppressed and which is excellent in the design, and which presents a low environmental impact, its production method and an article having its surface treated with the water/oil repellent composition.
A water/oil repellent composition comprising a polymer having structural units based on the following monomer (a) and structural units based on the following monomer (b), and an aqueous medium containing water and the following amide solvent (I) is used. Monomer (a): a compound represented by (Z-Y)nX, wherein Z is a C1-6 polyfluoroalkyl group or the like, Y is a bivalent organic group having no fluorine atom or the like, n is 1 or 2, and X is a polymerizable unsaturated group. Monomer (b): vinyl chloride. Amide solvent (I): a compound represented by R1O(CH2)r(CHR4)sC(O)NR2R3, wherein r is an integer of from 0 to 3, s is 0 or 1, R1 is a C1-3 alkyl group, each of R2 and R3 is a methyl group or the like, and R4 is a hydrogen atom or the like.
