Then, 264.4 g of water was added thereto, and 656.4 g of the resorcinol/formaldehyde mixed liquid prepared as described above, was mixed thereto. The mixture was left to stand and aged at 23° C. for 24 hours to obtain a resorcinol/formaldehyde/latex mixed liquid (the weight ratio of the latex solid content to the sum of resorcinol and formaldehyde: 1/0.86, total amount of surfactant: 0.74 wt %).
