<p>Improved durability and water repellency are provided to porous substrates by the use of a novel penetrating treatment composition comprising (A) C10 to C22 alkyl acrylate(s) or methacrylate(s) which are non-oxidizing and polymerizable to form homopolymers having a glass transition temperature of about 0 DEG C or less and (B) autoxidative compound(s) which function as polymerization initiator-oxygen scavenger, wherein the weight ratio of (A) to (B) is about 50 to 95 to about 50 to 5.</p> |
