  • Patent number: 9216397
    Abstract: 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.
