Capsule-coated record sheet (with subcoat of latex)
Abstract
Abstract THIS INVENTION RELATES TO PRESSURE-SENSITIVE RECORD SHEET MATERIAL INCLUDING A BASE RECORD MATERIAL SHEET HAVING AT LEAST ON ONE SURFACE A SUBCOATING OF LATEX MATERIAL OVER WHICH IS COATED A LAYER OF PRINTING-LIQUID-CONTAINING PRESSURE-COATED SIDE AGAINST A SHEET SENSITIZED TO REACT WITH LIQUID RELEASED BY IMAGING PRINTING PRESSURE MADE AGAINST THE CAPSULE-COATED SHEET TO YIELD A DISTINCTIVELY-COLORED IMAGE. THE LATEX COATING SERVES THE PURPOSE OF CUSHIONING THE CAPSULES AGAINST RUPTURE BY CASUAL PRESSURE OCCURRING IN HANDLING, ROLLING, AND STACKING OF THE SHEET MATERIAL, AND ASSISTS IN THE TRANSFER OF CAPSULE-YIELDED LIQUID TO THE SENSITIZED SHEET BY RESISTING WETTING OF THE CAPSULE-BEARING BASE SHEET BY THE LIQUID RELEASED FROM THE RUPTURED CAPSULES.
