Ektaflex PCT

“In 1981 Eastman Kodak introduced an innovative product, Ektaflex PCT (Photo Color Transfer), which allowed photographers to instantly print enlarged negatives or transparencies. Up to this time only in-camera picture taking had been possible with instant materials. The image formation in Ektaflex PCT featured a dye release system similar to that of Kodak’s integral films. To make a print, a color negative or transparency was inserted into an enlarger and projected onto an Ektaflex PCT Negative or Reversal Film. After exposure, the film was loaded into a special Kodak Printmaker processor, where it was soaked in a chemical activator (Kodak PCT Activator, supplied ready for use) and then pressed into contact with a sheet of Ektaflex PCT Paper (a resin-coated receiver sheet). After ten minutes, film and paper were peeled apart and the film was discarded (Fig. 7.14) (Eastman Kodak 1981).”
