Patent application number | Description | Published |
20120205386 | Thermochromic Coatings With Resin Vehicle - Thermochromic coatings are improved by mixing thermochromic capsules with polymer resins in a manner that imparts shelf stability to flowable precursors that may be cured to form relatively hard coatings that are capable of withstanding machine operations, such as the operations needed to make beverage can lids, bottle caps, pull tabs and the like. | 08-16-2012 |
20120315412 | Scented Thermochromic Ink - A thermochromic ink contains scented microcapsules. | 12-13-2012 |
20130075675 | Thermochromic Compositions From Trisubstituted Pyridine Leuco Dyes - A thermochromic leuco dye composition contains a leuco dye moiety including one or more tri-aryl substituted pyridines, a UVA developer moiety including at least one UVA developer selected from the group consisting of salicylic acid and derivatives thereof, and biphenyls and derivatives thereof, and a carrier selected from the group consisting of a fatty ester, fatty alcohol, fatty amide, and combinations thereof. | 03-28-2013 |
20130105743 | Photochromic Inks | 05-02-2013 |
20130177703 | REVERSIBLE THERMOCHROMIC AND PHOTOCHROMIC INK PENS AND MARKERS - Reversible thermochromic and photochromic ink compositions and markers, pens or writing instruments that use them are herein disclosed. | 07-11-2013 |
20130231242 | PRESSURE SENSITIVE COATING FOR IMAGE FORMING - Dye and developer components of a leuco dye system are separately microencapsulated. The microcapsule walls are fragile to the point of being easily ruptured. The microcapsules are mixed combined into a coating composition that is applied to a substrate and dried. Forces applied to the substrate, such as by the application of fingers or a writing instrument, rupture the capsule to produce a color change by interaction of the leuco dye system components that are released upon rupture of the capsules. | 09-05-2013 |
20130340885 | Thermochromic Level Indicator - A thermochromic ink or print varnish is formulated and printed to form a level indicator. | 12-26-2013 |
20140039091 | Interactive Coating for End Printing - Thermochromic coatings are improved by mixing thermochromic capsules with polymer resins in a manner that imparts shelf stability to flowable precursors that may be cured quickly using dodecylbenzenesulfonic acid and/or other acid catalysts to form relatively hard coatings that are capable of withstanding machine operations, such as the operations needed to make beverage can lids, bottle caps, pull tabs and the like. | 02-06-2014 |
20140187668 | STABILIZING ADDITIVES FOR THERMOCHROMIC PIGMENTS - A microencapsulation process is improved by adding a stabilizing agent that contains one or more catalytic organo-metal oxide materials, such as metal soaps. This functions as a crosslinker by causing unsaturated bonds in the microcapsule walls to react, thereby stabilizing the microcapsules against the effects of additives to coatings that, otherwise, degrade the functionality of thermochromic or photochromic materials at the microcapsule core. | 07-03-2014 |
20140210201 | VARIABLE PRINTING OF THERMOCHROMIC CODES - Promotional codes are printed using thermochromic inks in a manner that conceals the codes until a beverage or other article is cooled sufficiently to reveal the codes. | 07-31-2014 |
20140212654 | PRESSURE SENSITIVE COATING FOR IMAGE FORMING - A microencapsulated pigment including a leuco dye system is incorporated as one or more layers in a roll of adhesive tape. The tape is applied and may be rubbed by hand or another object to induce a color change. The change may serve as an indicator that the tape is well adhered for masking purposes in a painting operation, or to present a design where only selected portions of the tape are rubbed to induce the color change. The microencapsulated pigment may be constructed so that the color change is irreversible or reversible. | 07-31-2014 |
20140213442 | THERMOCHROMIC COLORING PAD - A children's coloring pad may incorporate thermochromic pigments that are specially formulated to develop color and clear color by respective applications of cold and hot temperatures. The pad may be used in a similar manner as with respect to finger painting, but without the residual mess. | 07-31-2014 |
20140272161 | SMALL SCALE MICROENCAPSULATED PIGMENTS AND USES THEREOF - A method is provided for making thermochromic pigments in microcapsules having unusually small particle sizes. | 09-18-2014 |
20140366238 | Water-Activated Thermochromic Materials - An article of clothing is coated or impregnated with a coating that contains thermochromic pigment. The pigment is constructed to change color when wet with water, and/or to provide a hyperthermic warning when a person wearing the clothing is over-warm. | 12-18-2014 |
20150018441 | YELLOW THERMOCHROMIC DYES, INKS COMPOSITION AND LEVEL INDICATORS - A new leuco dye produces a yellow color while demonstrating also exceptional light and thermal stability under light. | 01-15-2015 |
20150076423 | SMALL SCALE MICROENCAPSULATED PIGMENTS AND USES THEREOF - A method is provided for making thermochromic pigments in microcapsules having unusually small particle sizes. | 03-19-2015 |
