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.

Laser thermal metallic donors

A laser-induced thermal imaging system having a donor element and a receptor element. The donor element includes a substrate on which is coated transfer material that includes: a binder including a hydroxylic resin; a fluorocarbon additive; a cationic infrared absorbing dye; a dihydropyridine latent crosslinking agent; and a dispersible material. The receptor element comprises a texturized surface.

Laser induced film transfer system

An imaging method is provided that includes a tetraarylpolymethine dye, and bleaching this dye by bringing the dye into contact with a 4-alkyl or 4-unsubstituted 1,4-dihydropyridine derivative.

Thermal bleaching of infrared dyes

An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.
