<P>PROBLEM TO BE SOLVED: To provide a composition that imparts excellent water absorbing ability, oil repellency, stain proofness and stain removing property to a fiber woven fabric or the like and that has the same excellent properties even if the number of carbon atoms in an Rf group is so small as less than 8 compared with those of conventional ones. <P>SOLUTION: The composition contains: (1) a fluorinated copolymer that contains, as essential components, (a) a fluorinated monomer represented by general formula CH<SB POS="POST">2</SB>=C(-X)-C(=O)-Y-[-(CH<SB POS="POST">2</SB>)<SB POS="POST">m</SB>-Z-]<SB POS="POST">p</SB>-(CH<SB POS="POST">2</SB>)<SB POS="POST">n</SB>-Rf (I) [wherein Z is a direct bond, -S- or -SO<SB POS="POST">2</SB>-, Rf is 1-6C fluoroalkyl, m is 1-10, n is 0-10, and p is 0 or 1] and (b) an alkoxy group-containing monomer represented by general formula CH<SB POS="POST">2</SB>=C(X')-C(=O)-O-(RO)<SB POS="POST">q</SB>-H (II) and that does not contain any amino group-containing monomer; (2) a block isocyanate compound; and (3) a liquid medium. <P>COPYRIGHT: (C)2013,JPO&INPIT |
