The present invention provides a water and oil proofing composition which imparts excellent water and oil resistance. A composition which comprises a fluorocopolymer comprising polymerized units of (Z-Y)<SUB>n</SUB>X (wherein Z: a C<SUB>1-6 </SUB>perfluoroalkyl group or the like, Y: an alkylene group or the like, n: 1 or 2, X: a polymerizable unsaturated group), polymerized units of CH<SUB>2</SUB>-CR<SUP>1</SUP>-G-(R<SUP>2</SUP>O)<SUB>q</SUB>-R<SUP>3 </SUP>(wherein R<SUP>1</SUP>: a hydrogen atom or the like, R<SUP>2</SUP>: a C<SUB>2-4 </SUB>alkylene group or the like, q: an integer of from 1 to 50, G: -COO(CH<SUB>2</SUB>)<SUB>r</SUB>- (r: an integer of from 0 to 4), R<SUP>3</SUP>: a hydrogen atom or the like) and polymerized units of CH<SUB>2</SUB>-CR<SUP>4</SUP>-M-Q-NR<SUP>5</SUP>R<SUP>6 </SUP>(wherein R<SUP>4</SUP>: a hydrogen atom or the like, Q: a C<SUB>2-4 </SUB>alkylene group or the like, R<SUP>5 </SUP>and R<SUP>6</SUP>: C<SUB>1-8 </SUB>alkyl groups or the like) and an aqueous medium.
