Abstract

Abstract PURPOSE:To provide the thermo sensitive recording sheet for preventing its slip when it is fed and for enabling a recording of a clear image having no distortion by a method wherein a slip prevention agent is coated on the back surface of a supporter member having a thermo sensitive colouring layer at its front surface. CONSTITUTION:In the thermo sensitive recording sheet containing a colouring substance of noncolour or a light colour (Ex: crystal violet lacton etc.) and a developing substance for developing said colouring substance (Ex: bisphenol A etc.), a slip preventing agent (Ex: more than one kind of carbonate calcium, rosin etc.) is coated on the back surface of the supporter member to get the desired sheet. The slip prevention agent is dispersed in a binder (Ex: hydroxyethylcellurose) for its practical use. Thereby, no slip is found even in a high speed recording.
