반응 단계
Formaldehyde (50%, 12.0 g, 0.2 mol) was added to a mixture of melamine (12.6 g, 0.1 mol) and water (40 ml) with stirring. The pH of the mixture was adjusted to 9.0-9.2 by addition of NaOH (0.5N). The mixture was heated to 70° C. and a dyestuff (Direct red 252 mg, 2000 ppm based on melamine) was added to give a colored methylolmelaminersolution. In this procedure, other dyestuffs can be used such as direct dyes, fluorescent dyes, dispersion dyes, and mixtures thereof. See Table 1.
