ABSTRACT:
An erroneously recorded image among recorded images on a recording medium is corrected by a correction sheet comprising an adhesive layer on a support. The adhesive layer is heated to develop an adhesive force and caused to adhere to the error image and peel the error image when the correction sheet is separated from the recording medium. The adhesive layer comprises a laminate structure including a separation prevention layer and an upper layer, and the separation prevention layer is in charge of cohesion strength, intimate adhesion to support and flexibility under heating of the adhesive layer. Because of the laminate adhesive layer structure, the correction sheet allows for adequate correction of an error image even on a recording medium with poor surface smoothness without causing correction failure, such as reverse transfer.
