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.

Abstract:
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.
Reversible Thermochromic And Photochromic Ink Pens And Markers
The present disclosure is a method for controlling the hysteresis window and improving the color switching properties of reversible thermochromic dye systems. The method adds preferred co-solvents to existing reversible thermochromic dye systems in order to decrease the temperature range between the full color point and the clearing point. The co-solvents also add resistance to ultraviolet radiation.
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.

Abstract:
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.
