Microencapsulated imaging system

Figure 1. Schematic representation of the microencapsulated imaging system A-microcapsule internal phase, B-transparent shell, C-substrate, D-dye developer layer.

Experimental work reported below shows that such tests can be used to predict microencapsulated system behavior and its imaging characteristics. It also demonstrates that the microcolumn imaging system provides a convenient vehicle for observations with SEM and other analytical methods,including GC, IR and TA. 

Photographic behavior of the microcolumn imaging system parallels the microencapsulated system in many respects. Microcolumn provides a convenient sampling format for application of the multi-technique approaches in addressing the interdependence of the imaging characteristics, curing conditions, and the structure of the polymer formed.
