Preparation of high pressure decorative laminates having registered color and embossing using encapsulated ink

Abstract

Abstract D R A W I N G IN THE MANUFACTURE OF HIGH PRESSURE DECORATIVE LAMINATES HAVING EMBOSSED SRFACES WITH REGISTRATION OF COLOR AND TEXTURE, A MELAMINE IMPREGNATED PAPER, COATED WITH ENCAPSULATED INK, IS USED IN PLACE OF THE CONVENTIONAL DECORATIVE SHEET BELOW THE OVERLAY SHEET. A SCULPTURED PLATE IS USED HAVING HIGH PRESSURE AREAS AND LOW PRESSURE AREAS, THE ENCAPSULATED INK SURFACE BEING SEPARATED FROM THE SCULPTURED PLATE BY THE OVERLAY AND A RELEASE LAYER. THE RESULTING LAMINATE AFTER PRESSING HAS COLOR DEVELOPED BY THE RUPTURE OF THE MICROCAPSULES AND RELEASE OF THE INK CONTAINED THEREIN AT AREAS CORRESPONDING TO HIGH PRESSURES DUE TO THE PRESENCE OF AND SHAPE OF THE SCULPTURED PLATE, WHEREAS IN THE AREAS OF LOWER PRESSURE THE MICROCAPSULES REMAIN UNRUPTURED.
