Claims
- 1. In a multi-level, embossed, dimensionally stable surface covering comprising:
- (a) a main body layer having at least in part a top surface and a bottom surface, said layer being comprised of a fused matrix resinous dryblend containing homogeneously distributed therein originally hollow non-thermoplastic particles;
- (b) first depressed portions on said main body layer, said depressed portions comprising fused resin in a substantially continuous phase and substantially completely crushed non-thermoplastic particles,
- (c) raised portions on said main body layer elevated with respect to said depressed portions and comprising fused resin in a relatively non-continuous phase with non-crushed and substantially only partially crushed non-thermoplastic particles therein;
- (d) a first substantially impermeable transparent fused resinous wear layer overlying the main body layer, and
- (e) a second substantially impermeable fused resinous layer bonded to the top surface of the main body layer and to the bottom surface of the wear layer.
- 2. In a multi-level, embossed, dimensionally stable surface covering as set forth in claim 1 wherein the first substantially impermeable transparent fuse resinous wear layer is a rigid vinyl having a three to five percent plasticizer level.
- 3. In a multi-level, embossed, dimensionally stable surface covering as set forth in claim 1 wherein the second substantially impermeable fused resinous layer is the same composition as the main body layer composed of resinous dryblend except the second layer has less originally hollow non-thermoplastic particles therein.
