摘要
PURPOSE: A manufacturing method of a resist printing melamine resin and a resist printing melamine sheet manufactured by using the method are provided to manufacture an improved resist printing melamine resin which maintains advantages of existing melamine resin and can be conveniently produced and used.;CONSTITUTION: A manufacturing method of a resist printing melamine resin comprises following steps: a pre-condensation step which adds formalin and melamine in a condition with pH 7-10 at less than 40deg.C and gradually increases temperature to 80-100deg.C; a condensation step which polycondenses the reactant in pH 7-10 at 80-100deg.C and adds a resist printing compound to the reactant. A molar ratio of the formalin and melamine is 1.4-2.1. 1-10 parts by weight of a resist printing melamine resin are added based on amount of the reactant.;COPYRIGHT KIPO 2012
