Abstract

PURPOSE: To provide the titled, molding material which does not suffer from fogging during molding and gives molded articles having excellent appearance and luster, by using an amino resin having a specified methylenation rate.
CONSTITUTION: An amino compd. (e.g. melamine) and an aldehyde (e.g. HCHO) are blended together in a predetermined molar ratio. The mixture is adjusted to a neutral pH or an alkaline pH by using a basic material (e.g. NaOH), and then subjected to a reaction at 40W100°C to such an extent that methylenation rate reaches 5W15wt%, to produce a liquid amino resin precondensate. A substrate such as pulp is impregnated with said amino resin precondensate, and dried by heating it at 70W 90°C to produce an amino-resin impregnated dried material. Then a hardener (e.g. hexamethylenetetramine), a parting agent (e.g. stearic acid) and a colorant are blended with said dried material. The mixture is mixed together and crushed to produce the desired amino resin molding material.
