Abstract
Composites useful in building structures such as floor tiles, are prepared having a very strong bond between a highly filled polymeric surface layer and a cementitious backing. The composite comprises: a first layer of solid particles intimately mixed with a polymeric binder; a second layer of an organic and/or inorganic solid; and a transitional layer located between the first and second layers comprising both the polymeric binder and the organic and/or inorganic solids 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.
