Abstract
This invention discloses a decorative sheet having a hammer tone texture and the method used to obtain such hammer tone texture. A hammer tone composition is agitated, applied to a decorative sheet using a controlled means of delivery in a sufficient thickness, and then dried at a sufficient temperature and for a sufficient time to provide the hammer tone texture on the decorative sheet.
Claims6
A decorative sheet having a hammer tone texture, comprising a backing sheet having a thickness within the range between 20 and 200 .mu.m, primer layer on the backing sheet, said primer layer consisting essentially of vinyl acetate resin and having a thickness within the range between 0.1 and 100 .mu.m, and a decorative layer on the primer layer, said decorative layer having a thickness within the range between 30 and 150 .mu.m formed by applying the decorative layer in the form of a hammer tone coating composition using a controlled means of delivery of the composition to the primer layer at a sufficient thickness after mixing with agitation time between 10 and 50 minutes at 500 revolutions per minute or below 50 minutes at 1000 revolutions per minute and then drying for a period of time ranging from 1 to 15 minutes at a temperature ranging from 120.degree. C. to 200.degree. C. in order to form a surface having a surface roughness Ra of 6 .mu.m or more.
A method of making a decorative sheet having a hammer tone texture comprising the steps of:
- (a) agitating a hammer tone coating composition for a time between 10 and 50 minutes at 500 revolutions per minute or below 50 minutes at 1000 revolutions per minute;
- (b) priming a backing sheet having a thickness within the range between 20 and 200 .mu.m with a primer layer, wherein primer layer consists essentially of a vinyl acetate resin and has a thickness within the range between 30 and 150 .mu.m;
- (c) applying the agitated hammer tone composition to the primer, layer using a controlled means of delivery of the composition at a sufficient thickness to provide a stereoscopic appearance;
- and
- (d) drying the applied hammer tone composition for a period of time ranging from 1 to 15 minutes at a temperature ranging from 120.degree. C. to 200.degree. C. in order to form a surface on the backing sheet having a surface roughness Ra of 6 .mu.m or more and having a thickness within the range between 30 and 150 .mu.m.
