Procedure

Apart from the above, melamine powder was added to an aqueous solution of 37% formaldehyde. This was controlled to have a pH of 9 with an aqueous solution of sodium hydroxide added thereto, and then heated at 60° C. for 30 minutes to obtain a melamine-formaldehyde prepolymer (this is a shell-coating resin).
