Abstract
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.

Type consisting of a heat-curable resin and comprising:
- a typeface portion consisting of particles of a first size having a hardness capable of withstanding pressure applied at printing and a particle size affording smoothness;
- an impact face portion consisting of particles of a second size larger than the first size and having a hardness capable of withstanding pressure applied at printing and an elasticity capable of withstanding and of absorbing impact sustained at printing;
- and
- a joint portion located between said typeface portion and said impact face portion and consisting of a mixture of the particles of the first size and the particles of the second size.
