Abstract

See full text

A laser-induced thermal imaging system having a multi-layer construction donor element and a receptor element for the preparation of a metallic digital half tone color proof having an improved shiny metallic appearance. The donor element includes a substrate on which is coated at least two layers. The donor element includes a first layer coated on one side of the substrate having at least a first donor binder and a cationic infrared absorbing dye. The donor layer also includes a distinct second layer coated on the first layer. The second layer includes at least a second donor binder, a cationic infrared absorbing dye, a latent crosslinking agent, a fluorocarbon additive, metallic flakes and a dispersible material. The receptor element of the present invention includes a substrate coated with at least a receptor binder and a bleaching agent.
