ABSTRACT:
The invention relates to a peel-apart, single sheet color proofing system capable of producing a negative image on a receiver sheet upon exposure to infrared laser radiation and peel development. The invention provides a negative working thermal imageable element for infrared laser imaging having a substantially transparent substrate, an infrared radiation sensitive, crosslinked thermal transfer layer on a surface of the substrate having a substantially uniform admixture of carbon black and a crosslinked polymer, a color layer on the crosslinked thermal transfer layer having a substantially uniform admixture of an organic binder and a colorant, and a thermoplastic adhesive layer on the color layer. The invention also provides a method for producing a negative image and a method for producing a negative working thermal imageable element.
