Correction sheet and correction method

In a correction method for correcting a recorded image on a recording medium formed by superposing a transfer ink sheet on the recording medium, heating the transfer ink sheet in a pattern with a thermal head and separating the transfer ink sheet from the recording medium to leave recorded ink images on the recording medium wherein a correction sheet having an adhesive layer on a support is heated sufficiently with the thermal head, caused to adhere to an erroneously recorded image among the ink images on the recording medium and then separated from the recording medium to peel the erroneously recorded image from the recording medium;

• the improvement wherein the adhesive layer of the correction sheet comprises a separation prevention layer comprising a thermoplastic resin having a glass transition temperature of -40.degree. to 30.degree. C. and an upper layer developing an adhesion on heating and containing a resin having a glass transition temperature of 60.degree. C. or higher in a proportion of 1-25 wt. % disposed in that order on the support;
• the positions of the separation of the correction sheet and the transfer ink sheet relative to the thermal head are made different from each other by the action of a peeling member movable toward and away from the recording medium;
• and the correction sheet is preliminarily heated prior to its contact with the erroneously recorded image and then further heated so as to adhere to the erroneously recorded image.
