Abstract
An anti-soil finishing agent is produced by copolymerizing a fluoroalkyl group-containing monomer with a hydrophilic group-containing monomer in polypropylene glycol having an average molecular weight of not more than about 1,000 or a mixture thereof with a water-soluble organic solvent having a boiling point of not less than 150° C. or a flash point of more than 61° C. The anti-soil finishing agent has not only a high flash point, but also distinguished frozen stability and high temperature stability (storage stability at a temperature of about 40˜50° C. higher than room temperature).
