Abstract
Methods for generating a color image are provided which include a multi-layer construction in which at least one of the layers is a thermally activatable layer that includes a thermally activatable composition. The thermally activatable composition includes a non-linear light to heat converter composition and a color forming compound. Upon activation with a light source an image forms.
Claims20
