Abstract
A laminate and the method for its formation are provided. The laminates comprise one or more polymeric layers and a surface coating layer which has been cured utilizing a specific sequence of ultra-violet (UV) irradiation, germicidal irradiation, and heat treatment. The laminates are produced by a process which imparts an aesthetically pleasing low-gloss finish to the crosslinked surface layer. Advantageously, the laminates can be used to realistically simulate patterns, wood, and wood grain finishes as they demonstrate enhanced depth of grain and print.
Claims23
A method for producing a laminate comprising the steps of:
- exposing a laminate comprising a substrate and a radiation curable surface coating to:
- a) a first source of UV radiation having a wavelength of from above about 240 to about 450 nm and an intensity from about 19.7 to about 236 watts/linear cm;
- b) germicidal radiation having a wavelength of from about 100 to about 240 nm and an intensity from about 0.39 watts/linear cm to about 7.87 watts/linear cm;
- and
- c) a second source of UV radiation having a wavelength of from about 240 to about 450 nm and an intensity from about 19.7 to about 236 watts/linear cm;
- said coating being cured through said radiation exposure steps.
A laminate, comprising:
- a substrate layer;
- printing on at least a portion of said substrate layer;
- and
- a cured coating on said printing, said coating having a gloss of less than about 5.0 measured at a 60° angle using a Gardner gloss meter, said coating having a wrinkled surface.
