Procedure

A mixture of 6 parts of melamine, 11 parts of a 37% by weight aqueous formaldehyde solution, and 30 parts of water was heated to 60° C. and stirred at that temperature. After 30 minutes, a transparent mixed aqueous solution of melamine, formaldehyde, and a melamine/formaldehyde initial condensate was obtained. The pH of the mixed aqueous solution was 6 to 8. This aqueous solution is hereinafter referred to as an "initial condensate solution".
