Abstract
An ink is used for forming a photothermal conversion layer used for causing expansion of at least a portion of a thermal expansion layer of a thermally-expandable sheet. The ink includes an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum. A base of the ink is white.
Claims19
An ink for forming a photothermal conversion layer used for causing expansion of at least a portion of a thermal expansion layer of a thermally-expandable sheet, the ink comprising:
- an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum, wherein
- a base of the ink is white.
A manufacturing method for manufacturing a shaped object by using a photothermal conversion layer for causing expansion of at least a portion of a thermal expansion layer of a thermally-expandable sheet, the manufacturing method comprising:
- forming the photothermal conversion layer using an ink on at least one surface of the thermally-expandable sheet, the ink comprising an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum, a base of the ink being white;
- and
- irradiating the photothermal conversion layer with light to cause expansion of the thermally-expandable sheet.
A thermally-expandable sheet comprising:
- a thermal expansion layer that distends due to heat;
- and
- a photothermal conversion layer disposed on at least one surface of the thermally-expandable sheet, the photothermal conversion layer for causing the thermal expansion layer to distend, wherein
- the photothermal conversion layer comprises an ink comprising an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum, a base of the ink being white.
