Abstract
Abstract An imaging system wherein a structure comprising a cohesively weak imaging layer sandwiched between a donor sheet and a receiver sheet is used. The imaging layer is activated with an activator comprising at least two components, one of the components being a plastic, the other being a partial solvent for the imaging layer. Upon separation of the receiver and donor sheets a durable, workable, plastic surface is obtained on the image. This surface may then be buffed providing a transparency which will project a true color image.
