Procedure
A mixture of 10 parts of melamine, 25 parts of a 37% formalin and 65 parts of water was adjusted to a pH of 9.0 with sodium hydroxide and heated to 60° C. to obtain a transparent aqueous solution of a melamine/formaldehyde initial condensate. This solution was added to the above emulsion, and the resulting mixture was stirred at 60° C. for 1 hour and then cooled to room temperature.
