Beschreibung
Zusammenfassung:	A soft water- and oil-repellent comprising, as an active ingredient, a copolymer of a perfluoropolyether alcohol (meth)acrylic acid derivative represented by the general formula: CH2=CR1COOCH2CF(CF3)[OCF2CF(CF3)]nOC3F7 [I](wherein R1 is a hydrogen atom or a methyl group, and n is an integer of 1 to 20), and a (meth)acrylic acid ester represented by the general formula: CH2=CR1COOR2 [II](wherein R1 is a hydrogen atom or a methyl group, and R2 is an alkyl group, an alkoxyalkyl group, a cycloalkyl group, an aryl group, or an aralkyl group) and having a glass transition temperature Tg of 51 to 120°C. The soft water- and oil-repellent gives a coating film formed from a coating agent which closely follows the deformation of rubber or resin, and exhibits water- and oil- repellency.
