Abstract
The present invention relates to compositions thermally curable on demand by red to near infrared irradiation, method of using same for thermal amplification of free radical polymerizations, and articles obtained by such method. The invention also relates to the use of a heat-generating dye in association with a thermal initiator for controlling the onset of thermal free radical polymerization.
