Type capable of being used for both printing and embossing consists of a heat-curable resin and is divided into three layers. The uppermost layer constituting a typeface portion employs a finely divided granular heat-curable resin and exhibits a high hardness and surface smoothness. The lowermost layer constituting an impact face portion employs a coarse granular heat-curable resin and exhibits low hardness and elasticity. An intermediate layer formed by mixing these two layers at the interface between them constitutes a joint portion exhibiting intermediate hardness.
