Abstract

Sheet, with porous, thin carrier paper and bonded, heat-shrinking, thermoplastic film, has thin coating, on film side, of release agent, in form of silicone resin or anionic surfactant, each melting in 60-200 degrees C range. This coating prevents film adhering to original when exposed to I.R. radiation. Perforation occurs rapidly. Both types of release agent have advantage of being cheap and readily available.
