Abstract
Aspects of the present invention relate to a resilient multilayer decorative surface covering and a method for producing a resilient multilayer decorative surface covering. The method comprises providing a substrate (36) and digitally embossing a coating on the substrate. Digitally embossing the coating comprises applying a plurality of plastisol or organosol layers (40a, 40b) so as to produce a coating having a three-dimensional surface relief, wherein at least one of the plurality of plastisol or organosol layers is structurally patterned.
Claims13
A method for producing a resilient multilayer decorative surface covering, the method, comprising:
- providing a substrate;
- and
- digitally embossing a coating on the substrate, wherein digitally embossing the coating comprises applying a plurality of plastisol or organosol layers so as to confer to the coating a three-dimensional surface relief, wherein at least one of the plurality of plastisol or organosol layers is structurally patterned;
- wherein applying the plurality of plastisol or organosol layers comprises:
- depositing plastisol or organosol on the substrate, the plastisol or organosol comprising a first plasticizer having a first solution temperature at the clear point, measured according to DIN 53408:1967-06 (5% S-PVC;
- K-value 71), the plastisol or organosol having an initial gelation temperature;
- applying, in a pattern, a second plasticizer on the deposited plastisol or organosol, the second plasticizer having a second solution temperature at the clear point, measured according to DIN 53408:1967-06 (5% S-PVC;
- K-value 71), the second solution temperature at the clear point being different from the first solution temperature at the clear point, so as to impart to the deposited plastisol or organosol a spatially modulated gelation temperature between a lowest gelation temperature and a highest gelation temperature;
- heating the plastisol or organosol to a heating temperature comprised between the lowest gelation temperature and the highest gelation temperature of the plastisol or organosol so as to selectively gel the plastisol or organosol in areas where the gelation temperature is lower than the heating temperature;
- and
- removing the plastisol or organosol so as to keep the selectively gelled plastisol or organosol areas on the substrate, thereby producing a structurally patterned plastisol or organosol layer.
