Peel development

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-...

This peel-developed system presents an unusual and, at the time of its somewhat serendipitous discovery, unexpected implementation of surface and interfacial phenomena to create a convenient method of graphic reproduction. At the same time,...

A fundamental study was conducted to determine the root causes of the orange peel in rotational molding. The effects of material properties such as density, rheological, thermal and powder properties, and process parameters were investigated. In addition, comparisons are made between the dry blended and melt blended samples in terms of orange peel development.
