Abstract
Methods for providing surface coverings with differential gloss, and surface coverings prepared by the method, are disclosed. The methods involve screen printing or rotogravure printing a relatively low gloss primer onto portions of a substrate surface covering. The primer-coated substrate is then coated with a relatively higher gloss coating composition, and the coating compositions are cured, advantageously in a single curing step. The result is a surface covering including a top coat having a lower gloss level overlying the primer and a higher gloss level in the regions not overlying the primer.
Claims43
A surface covering comprising:
- a) a surface covering substrate having a top surface and a bottom surface, wherein the top surface defines a continuous top layer,
- b) a primer overlying a portion of the continuous top layer, wherein the primer comprises a flatting agent, and
- c) a top coat overlying at least a portion of the primer and overlying substantially all of the top surface of the surface covering substrate,
- wherein the top coat overlying the primer has a gloss level less than the gloss of the top coat not overlying the primer, and wherein at least one portion of the top coat not overlying the primer is in direct contact with the continuous top layer of the substrate.
A method of making a surface covering having regions of different gloss level, comprising:
- a) providing a surface covering substrate having a top surface and a bottom surface, wherein the top surface defines a continuous top layer,
- b) applying a primer composition to a portion of the continuous top surface, wherein the primer composition comprises a flatting agent,
- c) applying a top coat composition to at least a portion of the primer and substantially all of the top surface of the surface covering substrate, and
- d) then curing the top coat composition,
- wherein the gloss level of the top coat overlying the primer has a gloss level less than the gloss of the top coat not overlying the primer, and wherein at least one portion of the top coat not overlying the primer is in direct contact with the continuous top layer of the substrate.
