摘要

This patent filing published in February 2014 assigned to Chromatic Technologies Inc., Colorado Springs, CO, relates to improving the durability of thermochromic inks so that they are sufficiently hard enough to withstand common machine operations such as forming beverage can lids, bottle caps, pull tabs and the like. The filing states that conventional thermochromic inks are generally unsuited for these manufacturing stresses. The patent centers on a blend formulated with thermochromic microcapsules and polymer resins, resulting in a mixture to which is added a particular type of catalyzing acid that rapidly cures the inks without activating them.
