散となり、単一色となってしまう。Moreover, various methods can be mentioned as methods for incorporating dyes and pigments. For example, there are methods in which a dye and pigment are added to a thermosetting resin and a curing agent, and then the mixture is cured, and a method in which a thermosetting resin and a curing agent are mixed and the dye and pigment are added after curing has proceeded to a certain extent. Although there are no limitations on the method of adding dyes and pigments (-bloc, divided, continuous, etc.) and the order of addition, it is necessary to add dyes and pigments before the final stage of curing. That is, the dye and pigment must be contained in the thermosetting resin, and a simple thermosetting resin melts and mixes with the resin (5) to become homogeneously dispersed, resulting in a single color.
