Anti-soiling treating agent
 An anti-soiling treating agent comprising PA0 (a) a perfluoroalkyl-containing hybrid urethane compound (I) resulting from the addition reaction of two perfluoroalkyl-containing alcohols which have a difference in melting point of at least 20.degree. C. and are selected from compounds of the following formula EQU Rf--A--B--OH PA1 wherein Rf represents a linear or branched perfluoroalkyl group, A is the group --CH.sub.2 --.sub.l in which l is an integer of 0 to 5, the group ##STR1## in which R is a hydrogen atom, an alkyl group having not more than 12 carbon atoms or a substituted alkyl group, the group ##STR2## in which R is as defined above, a phenylene group, an ether linkage, or an ester linkage, and B represents an alkylene or aralkylene group having not more than 12 carbon atoms, or a derivative thereof containing an ether linkage, PA0 the mole ratio between the two alcohols being 33-67:67-33, with a polyisocyanate, or PA0 (b) a composition comprising the perfluoroalkyl-containing hybrid urethane compound (I) and a fluorine-free vinyl polymer (II) having a Rockwell hardness of 90 to 130, or PA0 (c) a composition comprising the perfluoroalkyl-containing hybrid urethane compound (I) and a perfluoroalkyl-containing vinyl polymer (III), or PA0 (d) a composition comprising the perfluoroalkyl-containing hybrid urethane compound (I), the perfluoroalkyl-containing vinyl polymer (III) and the fluorine-free vinyl polymer (II), and if desired, water and/or an organic solvent.
