A light-accumulating transfer sheet containing a light-accumulating pigment, comprising:
- a supporting layer;
- an adhesive layer formed on the supporting layer;
- a resin layer formed on the adhesive layer;
- an infrared absorption layer comprising an infrared absorbent formed on the resin layer;
- a microcapsule layer, in which microcapsules are dispersed, formed on the infrared absorption layer;
- and
- a pigment dispersion layer containing a light-accumulating pigment formed on the microcapsule layer,
- wherein the microcapsules comprise a heat-meltable content which is reversibly solidified and melted by heat from the infrared absorption layer and an encapsulant for encapsulating the heat-meltable content.
