Procedure

In order to prepare the pre-treating liquid, 22 g of resorcin, 29 g of a 37% aqueous solution of formaldehyde, 31 g of a 28% aqueous solution of ammonia and 500 g of water were mixed altogether, the mixture was stirred at a temperature of 25° C. for 3 hours to provide a resorcin-formaldehyde prepolymer solution, the resultant prepolymer solution was mixed with 418 g of NIPPOL 2518FS, the mixture was stirred at 25° C. for 48 hours to provide an RFL emulsion, and the emulsion was mixed with 162 g of SUMIKANOL 750.
