ABSTRACT:
The present invention provides a water and oil proofing composition which imparts excellent water and oil resistance and comprises a fluorocopolymer comprising polymerized units of (Z-Y)nX (wherein Z: a C1-6perfluoroalkyl group or the like, Y: an alkylene group or the like, n: 1 or 2, X: a polymerizable unsaturated group), polymerized units of CH2═CR1-G-(R2O)q—R3(wherein R1: a hydrogen atom or the like, R2: a C2-4alkylene group or the like, q: an integer of from 1 to 50, G: —COO(CH2)r— (r: an integer of from 0 to 4), R3: a hydrogen atom or the like, and polymerized units of CH2═CR4-M-Q-NR5R6(wherein R4: a hydrogen atom or the like, Q: a C2-4alkylene group or the like, R5and R6: C1-8alkyl groups or the like) and an aqueous medium.
