Abstract:
A high hardness, soft composite material which consists of an organic/inorganic composite material comprisingat least 60% by weight of inorganic components including an aggregate component of 2 to 70 mesh and a fine particle component of 100 mesh or smaller in a weight ratio of the aggregate component to the fine particle component of 1/10 to 10/1, wherein at least a part of the aggregate component is a transparent component with a surface covered with a pigment component, and 40% by weight or less of organic components, wherein the composite material has a surface Vickers hardness, measured according to JIS Z 2244, of at least 400 and a radius of curvature R, at which the material is bendable without being broken, of 25-1,000 mm based on a plate-shaped body having a 3 to 15 mm thickness.
