Abstract

1,246,636. Thermographic processes for producing lantern slides. RICOH K. K. Sept. 20, 1968 [Sept. 23, 1967], No. 44867/68. Heading G2C. A thermographic process for producing an original for projection comprises imagewise reflex exposing to heat an undrawn, and at least 80% transparent, polypropylene sheet so that the areas in contact with the infrared absorbent image wrinkle and form an opaque, undulated image; the polypropylene sheet being one which shrinks 2% or less on heating to 120‹ C. for a minute either axially or transversely.
