Procedure
Six parts of melamine, 11 parts of a 37% aqueous solution of formaldehyde and 30 parts of water were stirred while heating at 60° C. In 30 minutes, a clear aqueous solution of a mixture of melamine, formaldehyde and a melamine-formaldehyde initial condensate was obtained. The pH of the aqueous solution was 6-8. This aqueous solution of a mixture of melamine, formaldehyde and melamine-formaldehyde initial condensate is hereinafter referred to as an "initial condensate solution".
