Abstract: A pressure sensor and its use for visually determining whether a preselected pressure threshold has been achieved, for example during high pressure processing treatment of a foodstuff. The pressure sensor includes a contained color-changing system having a dye, a developer, and a solvent; upon achievement of the preselected pressure threshold, the dye and the developer interact, resulting in a visible color change. Further, the visible color change can be retained upon a decrease in pressure and upon an increase in temperature, thereby effectively recording the achievement of the preselected pressure threshold during the high pressure processing treatment.

Abstract: Described are novel photochromic naphthopyran compounds which exhibit a red coloring when in a red-colored state achieved upon exposure to ultraviolet light, whereby the red coloring has a lambda max in a range of between about 490 nanometers to about 510 nanometers or between about 490 nanometers to about 500 nanometers.

Abstract: A temperature sensor, and methods of making and using such a temperature sensor, whereby the temperature sensor includes a reversible thermochromic color-changing system having a dye, a developer, and a solvent. Upon exposure to a preselected temperature threshold, association or disassociation of the dye and the developer results in a visible color change. Further, the color-changing system includes a color-memory property which facilitates retention of the color change to effectively record exposure to the temperature threshold.

Abstract: A red leuco dye demonstrates unusually good thermal and photo stability. The red dye may be used with developers and wax carries for microencapsulation to form thermochromic pigments for use in inks, coatings and the like. This pigment is particularly desirable for use in metal-deco coatings, such as those used in aluminum cans in high beverage canning operations.

Abstract: A thermochromic indicator and its use for visually determining whether adjacent surfaces of overlapping edge portions of side-by-side roofing membrane segments have been sufficiently heated to a preselected temperature threshold to achieve a desired weld therebetween to correspondingly seal the roofing membrane seam.
