Abstract
A soil release composition comprising: PA1 (A) a polymer comprising 10 to 100% by weight of constituting units of the formula: ##STR1## wherein R.sub.f is a C.sub.3 --C.sub.21 fluoroalkyl group; R.sup.1 is a hydrogen atom or a C.sub.2 --C.sub.4 acyl group; R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are, the same or different, each a hydrogen atom, a methyl group or an ethyl group; A is a group of the formula: --CH.sub.2 CH(OR.sup.1)CH.sub.2 --OCO-- which R.sup.1 is the same as defined in the above, --CO--, --(CH.sub.2).sub.k N(R.sup.2)CO-- in which R.sup.2 is the same as defined in the above and k is an integer of 1 to 10, or --(CH.sub.2).sub.k -- in which k is the same as defined in the above; h is an integer of 0 to 5; p is an integer of 1 to 40; q and r are, the same or different, each an integer of 0 to 40, PA1 (B) a hydrophilic resin, and PA1 (C) optionally a water- and oil-repellent, a weight ratio of (A):(B):(C) being 5-95:95-5:0 or 1-95:5-95:1-50, which can impart stainproofing property with good durability to a substrate such as plastics, fabrics and paper.
