<p>PROBLEM TO BE SOLVED: To provide a latex for primer excellent in adhesiveness to a cement cured product without floating or cracking of an overcoating mortar composition and further excellent in water resistance and durability.SOLUTION: There is provided a latex for primer obtained by copolymerizing at least a carboxyl group-containing polymerizable monomer (A) of 0.5 to 10 mass%, alkoxy silane group-containing polymerizable monomer (B) of 0.05 to 5 mass%, an amide group-containing polymerizable monomer (C) of 0.05 to 5 mass% based on 100 mass% of the total weight of the polymerizable monomer and another polymerizable monomer (D) copolymerizable with any one or more kind of the (A) component, the (B) component and the (C) component.</p> |
