Abstract:
A composite structure suitable for a wide range of building products comprising:a first layer of solid particles mixed with a polymeric binder; a second layer of an organic and/or inorganic solid; an optional transitional layer located between the first and second layers comprising both the polymeric binder and the organic and/or inorganic solid, wherein the polymeric binder is contained in pockets within the organic and/or inorganic solid and at least some of the pockets of the polymeric binder extend from the first layer; and a third layer of a cured polymer resin in contact with at least one of the first, second, or transitional layers, the third layer having color different from the first layer; with the proviso that the transitional layer must be present unless the organic and/or inorganic solid is a cast structure having a smooth surface and the polymeric binder is curable with ultraviolet radiation; and with the additional proviso that when the organic and/or inorganic solid is a cast structure, then the polymeric binder is curable with ultraviolet radiation.
