Products using tire crushed rubber or recycled rubber chips as a base also have weak resistance to ozone and light. Further, when a pigment or the like is added to the binder in order to make the surface layer colored for the purpose of improving the aesthetic appearance, the strength peculiar to the binder is diminished in proportion to the addition amount of the pigment. Further, in the method of coating and coloring the surface layer, there is a problem that the colored portion is extremely thin and the appearance is impaired due to peeling of the coating or the like.
