Title: Ink, thermal expansion sheet, and manufacturing method of molded article
Inventor: TAKAHASHI HIDEKI
IPC: B41M5/00
Filed: 2018-04-27
Abstract: To provide an ink for forming a thermal conversion layer capable of reducing effect on hue of a molded article, a thermal expansion sheet using the same, and a manufacturing method of the molded article.SOLUTION: An ink contains a thermal conversion material for converting electromagnetic wave to heat, and a color adjustment agent developing a color which is a complementary color to a color developed by the thermal conversion material.
