Abstract
The invention relates to a thermal transfer sheet including a thermally transferable ink layer on one surface of a substrate film, wherein said ink layer contains a coloring agent, and a decoloring agent that prevents thermal color-developing paper from color development or makes the color, once developed thereby, invisible; a thermal transfer sheet including on one surface of a substrate film a first thermally transferable ink layer containing a decoloring agent that prevents thermal color-developing paper from color development or makes the color, once developed thereby, invisible, wherein at least one second thermal transfer ink layer is interposed between said ink layer and said substrate film; and a thermal transfer recording method that uses these thermal transfer sheets. Also, the invention relates to a rimmed image wherein at least an area of thermal color-developing paper is solid-heated for color development, and an image is formed in said color-developed area with the edge being rimmed in white or other color; and a method for forming a rimmed image.
