  • Publication number: 20060032427
    Abstract: A temperature indicating display device capable of displaying a thermo-history above a predetermined temperature reliably and irreversibly. Moreover, it is possible to provide a laminated body having a temperature detecting layer and an information recording film layer. When the temperature indicating display device is exposed to a predetermined temperature, an irreversible shift is caused and the temperature history can be displayed. Moreover, the temperature indicating display device includes an information recording film layer containing information, an information record holding layer for holding the information, and a temperature detection agent layer composed of a material whose state is shifted according to a temperature and is characterized in that when a predetermined temperature is detected, the material of the temperature detection agent layer is changed so as to change the display state of information recorded in the information recording layer.

  • Patent number: 5998089
    Abstract: Disclosed are a photosensitive resin composition containing a fullerene and a polymer compound bearing a functional group which can react with the fullerene under irradiation of visible light; method for forming negative-type picture elements comprising steps of: forming a layer composed of the above composition, irradiating the layer with visible light through a photo mask having a pattern transmitting the visible light as a part of the mask to cure portions of the layer irradiated by the visible light, and removing uncured portions of the layer to form a resist film having cured portions of the pattern: and a method for producing devices comprising steps of: forming a layer of the above composition on an image-forming layer provided on a substrate, irradiating the layer with visible light through a photo mask having a pattern transmitting the visible light as a part of the mask to cure portions of the layer irradiated by the visible light, removing uncured portions of the layer to form a resist film having
