PRESSURE-SENSITIVE RECORDING SHEET FOR PREVENTING ALTERATION

摘要

PURPOSE:To prepare a pressure-sensitive recording sheet for preventing alteration made impossible in the alteration due to a postentry. CONSTITUTION:The color forming layer formed to a support like paper using an electron donating dye (A) as a main component and an electron acceptive acidic substance as a color forming aid is opposed to the color forming layer formed to a support using an electron donating dye (B) having a color forming hue different from that of the dye A and the electron acceptive acidic substance as main components. When pressure is applied to both color forming layers, printing having the mixed hue of the dyes (A), (B) is obtained in both color forming layers only by the combination of both color forming layers to become the so-called alteration preventing recording and a pressure-sensitive recording sheet for preventing alteration having high practical value can be provided.
