TEMPERATURE SENSITIVE PRINTED MATTER

摘要

PROBLEM TO BE SOLVED: To provide a temperature sensitive printed matter capable of enjoying with a color changed when a stereoscopically processed image is brought into contact entirely or partly or a rough sketch present. SOLUTION: A temperature sensitive ink layer 3 is formed on at least part of a design of a protrusion and recess processed part E executed by a stereoscopic expression by protrusion and recess processing tuned with the design, and the layer 3 is reversibly changed to have a density concealing a rough sketch at the ambient temperature or to be colorless and transparent at a body temperature or reversibly changed to different colors at the ambient and body temperatures.
