Abstract
A temperature indicating composition is provided for use on a recoverable article so that heating to produce recovery or to activate a heat-activatable sealant can be monitored. The composition comprises a thermochromic colorant in a binder that can be cured by UV radiation. Such a composition can be applied rapidly to polyolefin substrates by printing.
