ABSTRACT:
A method and an apparatus for thermal recording and thermal transfer recording in a multicolor system. After performing the thermal recording, the thermal transfer recording is performed by overlaying a portion thermally recorded already. A thermal transfer donor sheet has a thermal transfer layer containing a desensitizer for suppressing a coloring reaction in the thermal recording layer of the thermal recording sheet. In performing multicolor recording by overlapping images of plural documents, after an image of a first document has been thermally recorded on a recording sheet, an image of a second document is recorded on the same recording sheet by thermal transfer recording. No color mixture occurs between colors thermally recorded and thermally transferred respectively and bright and clear color development can be obtained.
