PROBLEM TO BE SOLVED: To obtain the subject aqueous solution useful as a coating resin capable of forming a coating film having excellent water-repellence and water resistance by copolymerizing a mixture containing a monomer having a specific structure, a monomer having an alkoxysilyl group, an ethylenic unsaturated monomer, etc. SOLUTION: The objective aqueous solution is produced by copolymerizing a monomer mixture containing (A) 3-70 wt.% of one or more monomers selected from the monomer of the formula I (R<1> is H or methyl; R<2> is phenyl or a 1-6C alkyl; n<1> is 1-10; n<2> is 5-200) and the formula II (R<3> is H or methyl; X is H or F; n<3> is 1-8; n<4> is 1-30), (B) 1-40 wt.% of a monomer having an alkoxysilyl group; (C) 1-25 wt.% of anα,β-ethylenic unsaturated monomer having a functional group selected from carboxyl group, sulfonic acid group and amino group and (D) 0-95 wt.% of otherα,β-ethylenic unsaturated monomers. |
