    摘要： A device for indicating whether a rise in temperature above a predetermined value has occurred includes a support member, such as a label, on which a temperature-sensitive material is deposited. The material includes a large number of fracturable microcapsules containing a medium which changes from a solid state to a liquid state at the predetermined temperature value. The viscosity of the medium in its liquid state and the material of the support member are chosen such that the distance d.sub.1 by which the medium flows across the support member after the fracturing of the microcapsules so as to activate the device is indicative of the time between activation of the device and cooling of the device to below the predetermined temperature value. If the temperature is subsequently allowed to rise above the predetermined value, the medium will again assume its liquid state and will flow further across the support member, reaching a distance of, say, d.sub.2, thus indicating that the rise in temperature has occurred. The material may be printed on the label as a bar code, so that any rise above the predetermined temperature level will be indicated by distortion of the bar code which renders it unreadable.

    摘要： A hot melt ink comprising, a eutectic composition and an image-forming agent, wherein the melting point of the eutectic composition is from about 80.degree. C. to about 130.degree. C. and the compounds present in the eutectic compositions have melting points of at least about 100.degree. C. Also disclosed is a method for ink jet printing comprising:(a) providing a thermally reversible hot melt ink which is a solid at ambient temperature and a liquid at temperatures between about 80.degree. C.-130.degree. C., said ink comprising:(i) a eutectic composition; and(ii) an image-forming composition;(b) elevating the temperature of said eutectic composition to between about 90.degree. C. and about 140.degree. C., to cause said ink to form a liquid solution or suspension of said image-forming composition;(c) jetting said ink onto a substrate in the form of images;(d) allowing said ink to crystallize upon cooling on said substrate.
