Abstract
Surface covering components that include a topcoat layer with different gloss levels in various regions on the top coat layer, and methods of manufacturing such surface covering components, are disclosed. The surface covering components include a coating layer that includes regions that have a relatively higher gloss, and regions with a relatively lower gloss. The differential gloss is provided by coating a substrate with a UV-curable coating composition, subjecting a first region of the surface coating to polymerization under a first set of conditions, and subjecting a second region of the surface coating to polymerization under a second set of conditions. The UV-curable coating compositions include UV-curable components and one or more flatting agents. The different polymerization conditions involve applying various photoinitiators, thermal initiators and/or cure altering agents to some regions of the coated substrate, and not applying these components to other regions of the substrate. The components are applied in the form of a pattern. Regions in contact with these components are cured at different rates in one step or in different steps, for example, sequential UV and EB irra…
