Apart from this, by stirring a mixture of 6 parts of melamine, 11 parts of an aqueous solution of 37% by weight formaldehyde, and 30 parts of water for 30 minutes at 60° C., a transparent aqueous solution of a mixture of melamine, formaldehyde, and a melamine-formaldehyde initial condensate was obtained. The pH of the aqueous solution thus formed was from 6.0 to 8.0. Hereinafter, the aqueous solution of a mixture of melamine, formaldehyde, and a melamine-formaldehyde initial condensate is referred to as an initial condensate solution.
