PURPOSE:To enable a recording of superior image quality with good feeding properties, by a method wherein a coloring material layer is formed on one face of a base film and a heat resistant lubricating layer of a composition containing a cellulose acetate, an isocyanate compound, and a phosphoric ester group is formed on the other face thereof. CONSTITUTION:A coloring material layer containing a sublimating dye is formed on one face of a base film; a heat resistant lubricating layer is formed on the other face thereof by using a composition containing a cellulose acetate, an isocyanate compound having 2 or more-NCO groups, and a phosphoric ester group derived from a compound shown by a formula (I) (where R<1> represents alkyl, alkenyl, aralkyl, or aryl; R<2> and R<3> represent hydrogen atom or alkyl; and (n) represents an integer 1-50) and phosphoric acid. In the forming of the beat resistant lubricating layer, the isocyanate compound reacts with the cellulose acetate to enhance the heat resistance to heat resistant lubricating layer and adhesion to the base film. The phosphoric ester derived from the compound shown by the formula (I) and phosphoric acid is enhanced in heat resistance, lubricating properties, and antistatic properties, thus facilitating the feed of a thermal recording sheet in recording and enabling the prevention of the adhesion of residue to a thermal head. |
