Peel-developed imaging system

Figure 1 depicts the four-layer composite for the peel-developed imaging system comprising 1) a transparent,...

The process used to make the proof involves the same lamination, exposure, and peel-apart steps shown before. Different photoactive systems having variants on the peel-developable system, ie, dual exposures to achieve a right-reading image on receptor or transfer processes, are reported in the patent hterature (53,54). 

In the panoply of photoactivated imaging materials and processes, peel-developed systems constitute an intriguing but sparsely populated niche. Common to these systems is the need to photochemically differentiate adhesive forces within a collection of layers. In the past this has been accomplished through photopolymerization ( 1), apparent photocrosslinking (2,3,4), or photo-... 

Polaroid Integral Films. In 1972 the SX-70 automatic camera and integral film system were introduced (12,13). The SX-70 film provided images that required no timing and no peeling apart. Each film unit was ejected through processing rollers immediately after exposure. The entire development process took place within the film unit under ambient conditions. 

EUROSPRINT Proofing System. Froehhch, Helmut H. (Du Pont de Nemours G.m.b.H., 6078 Neu Isenburg, Fed. Rep. Ger.). Proc. SPIE—Int. Soc. Opt. Eng. 1991, 1458 (Print. Technol. Images, Gray Scale, Color), 51-60 (Eng.). EUROSPRINT laminated toning film, which is used in proofing to tone CHROMALIN (TM) photopolymer film is described. Development of this dry peel-apart system and its performance are described.
