Thermographic paper and manufacturing method thereof and thermographic printing paper using the thermographic paper and printing metod thereof

摘要

PURPOSE: Provided are a heat sensitive recording paper which prevents a heat sensitive coating layer from reacting chemically by the direct sunlight and is produced in a low production cost, a preparation method thereof, a heat sensitive printing paper using the same and a printing method thereof. CONSTITUTION: The preparation method of a heat sensitive recording paper comprises the steps of: applying a heat sensitive coating layer(30) on a stencil paper(10) wherein the heat sensitive coating layer has the smaller surface area than the stencil paper; and applying an over-coating layer(40) on the heat sensitive coating layer wherein the over-coating layer has the bigger surface area than the heat sensitive coating layer. The preparation method further comprises applying an adiabatic pigment layer on the stencil paper before applying the heat sensitive coating layer wherein the adiabatic pigment layer has the bigger surface area than the heat sensitive coating layer.
