Abstract
A method of forming an image comprising imagewise-exposing a thermal recording element to heat, the element comprising a support having thereon a thermally-sensitive layer comprising particles containing a colorant, the particles having a particle size between about 1 and about 25 .mu.m suspended in a matrix, the layer having an optical density no higher than about 0.5, the heating thereby causing the colorant to spread out from the particles into the matrix, thus increasing the optical density in the imagewise-exposed areas.
