Abstract

PURPOSE:To provide the thermo sensitive recording sheet for enabling an improvement over a stain or a slip of a platen roll found in case of a continuous longer hours recording operation by a method wherein a thermo sensitive developing layer containing some developing substances and colouring substances is made on a supporter member to form the thermo sensitive recording sheet having a gas permeability higher than a specified value. CONSTITUTION:The thermo sensitive recording sheet is provided in which the gas-permeability of the thermo sensitive recording sheet having the thermo sensitive colouring layer of a unit volume of 30-80gm/m<2> on the supporter element which contains a colouring substance showing no colour or a light colour at its room temperature (Ex: crystal violet lacton etc.) and the developing substance for developing said colouring substance when heated (Ex: bisphenol A etc.) is made to be more than 3,000 seconds (preferably more than 5,000 seconds). In order to have the as-permeability more than 3,000 seconds, a paper, a synthetic sheet of paper applied as the supporter element are used as a base member for the supporter element, both front and rear surfaces of the base element may be coated with resin (preferably, a polyvynil alcohol etc.). And as a resin binding agent for a liquid for making the thermo sensitive colouring layer, it is preferable to apply a hydroxyethyleellurose etc.
