Title:
REVERSIBLE HEAT-SENSITIVE RECORDING MATERIAL
Document Type and Number:
Japanese Patent JP3116971
Kind Code:
B2
Abstract:
PURPOSE: To intensify contrast, to enhance sensitivity and to strengthen resistivity against repetitive use by providing an unstuck part containing air therein between a heat-sensitive element and at least a part of a coloring or a light- reflective part of a coloring or a light-reflective element.
CONSTITUTION: A heat-sensitive element whose transparency varies reversibly depending on temperature and a coloring or a light-reflective element having a coloring or a light-reflective part in at least a part thereof are integrally stuck fast together, and thereby a reversible heat-sensitive recording material is made up. When making up the above-mentioned material, an unstuck part containing air therein is provided between the heat-sensitive element and at least a part of the coloring or the light-reflective part of the coloring or the light-reflective element. Thereby a reversible heat-sensitive recording material in intensified contrast, having enhanced mechanical strength and excellent in sensitivity and resistivity against repetitive use can be obtained.
