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.

SMALL SCALE MICROENCAPSULATED PIGMENTS AND USES THEREOF

Encapsulated thermochromic pigments having an ave diameter from 3 to 5 microns may be poorly suited for use as a metal decoration ink for high speed application to a metal can, as problems can arise in the ink rheology with this relatively large particle size which may lead to misting as the ink is transferred at very high speeds. The method for making encapsulated thermochromic pigments provided herein can produce particles with sub-micron dimensions, whereby the method incorporates an anionic surfactant and a deflocculant to provide a dewatered slurry containing the encapsulated thermochromic pigments, which can then be used to make inks that show considerably less misting and better transfer to metal cans at high production line speeds, such as speeds exceeding 1000, 1500, or 2000 cans per minute. Additionally, these encapsulated thermochromic pigments can be used in ink jet printing applications.

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.
