Abstract
A thermally expandable sheet includes: a thermally expansive layer formed on a one surface of a base; a first ink receiving layer that is provided on the thermally expansive layer for receiving ink; a film provided on the first ink receiving layer; and a second ink receiving layer that is provided on the film for receiving ink; wherein the first ink receiving layer is formed of a material that provides a texture a different from a texture of the second ink receiving layer.
Claims6
A 2.5D image forming method, comprising:
- using a thermally expandable sheet comprising a thermally expansive layer formed on one surface of a base, a first ink receiving layer that is formed on the thermally expansive layer for receiving ink, a film provided on the first ink receiving layer, and a second ink receiving layer that is formed on the film for receiving ink, the first ink receiving layer being formed of a material that provides a texture different from a texture of the second ink receiving layer;
- forming of a second image on the second ink receiving layer;
- removing at least a portion of the film and exposing the first ink receiving layer;
- forming of a first image on the first ink receiving layer that is exposed;
- forming of a first electromagnetic wave heat conversion layer for converting electromagnetic waves to heat on another surface of the base;
- and
- irradiating of the first electromagnetic wave heat conversion layer with electromagnetic waves thereby causing at least a portion of the thermally expansive layer to distend, wherein
- the film is removed such that a region where the second image is printed or to be printed remains.
