<P>PROBLEM TO BE SOLVED: To provide a treatment composition for a porous base material, which gives an excellent surface-antifouling property to a porous base material such as stone. Ž<P>SOLUTION: The treatment composition for a porous base material contains a (meth)acrylic acid ester containing a perfluoroalkyl group having an at most 6C perfluoroether group, an unsaturated compound containing a carboxylic acid group, a (meth)acrylic acid ester containing an oxyalkylene group, and a copolymer derived from an unsaturated compound having silicon. The composition is normally in a liquid state containing a solvent. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
