Title: Near infrared laser absorbing coating and method for using same in color imaging and proofing
Inventor: FOLEY DIANE M
IPC: B41M5/24
Filed: 1990-03-30
Abstract: A laser imaging material which can be effectively employed for color printing and proofing comprises a near infrared transparent support film which has a near infrared absorbing layer thereon.  The absorbing layer contains at least one sensitizer which is absorbent at a desired near infrared laser output wavelength and a decomposable binder. Laser radiation at the desired wavelength which acts upon the absorbing sensitizer causes rapid partial decomposition of the binder into gaseous and non-gase-ous products. The rapid expansion of the heated gases causes ablation of inert materials from the surface of said layer onto a re-ceptor sheet thus producing an imaged film (i.e., the laser imaging donor material) and a color print or proof (i.e., the receptor sheet) of reversed sign to the imaged donor material.
