PROBLEM TO BE SOLVED: To obtain a compsn. having an excellent capability to remove adhered stains without making it water repellent so that contamination from stains is prevented, by having, as the indispensable components, a resin having a reactive functional group with a specific range of glass transition temp., a curing agent having a functional group reactive with the above-described functional group, a silicate compd. and/or a condensate thereof and a compd. having specific ranges of b.p., m.p. and SP value. SOLUTION: This compd. has, as the indispensable components, a resin (A) having at least one reactive functional group in a molecule, the resin having a glass transition point of 20-120 deg.C and being selected from the group consisting of a vinyl, a polyester, an epoxy and a urethane resin, a curing agent (B) having a functional group reactive with the above-described functional group, a silicate compd. (condensate) having the formula: (R'O)4Si and a compd. having a b.p. in the range of 140-350 deg.C an m.p. in the range of 40-180 deg.C and an SP value in the range of 11-14, In the formula, R' is 1-12C alkyl, alkenyl, (alkyl)aryl or aralkyl. The combination of (the functional group of component A)/(the functional group of component B) is pref. epoxy/COOH, COOH/epoxy or OH/ blocked NCO.
