Abstract
1,044,364. Thermographic materials and processes. GEVAERT PHOTO-PRODUCTEN N.V. April 1, 1963 [March 30, 1962], No. 12881/63. Headings G2C and G2H. [Also in Division H1] A thermographic record of an original is produced by exposing an electrostatically charged photoconductive layer or a magnetizable layer to an original, developing the latent image with an infra-red absorbing, non-thermoplastic powder to produce a visible positive or negative image, thereby bringing or subsequently bringing the powder image into heat-conductable relationship with a heat-sensitive material which is less infra-red absorbing than the image and heating to produce a thermographic record. The heat sensitive material may be one which produces a coloured image or heating such as starch a quaternary iodide salt, zinc oxide or zinc halide/chloride-containing polymer, p-phenylene diamine/copper stearate, chloranil/antipyrine, iron/dodecyl gallate/phenylpyrazolidone, a diazonium salt/2, 3-dihydroxy-5-sulphonaphthalene/sodium stearate, or lead acetate or stearate/thioacetamide, or one which transfers to a receptor layer on heating such as a dyed wax layer. The powder image may be directly contacted with the heat-sensitive material or it may be first electrostatically transferred to a receptor sheet before contact with the heat-sensitive material. Alternatively, the powder image sheet may have a heat-sensitive layer on the back or if a heat-transferable material is used, the transferable layer may be transferred on to the back of the powder image sheet. Production of the electrophotographic powder image. A photoconductive layer is electrostatically charged, exposed to an original and developed with an infra-red absorbing, non-thermoplastic powder which may carbon, phthalocyanine, iron, lead, copper, zinc, silver, aluminium or calcium, "Bakelite" (Registered Trade Mark), a metal oxide or sulphide or an infra-red dyestuff precipitated on to silica. The powder image may be electrostatically or magnetically transferred to a receiving sheet. After the image is used in producing the thermographic record, it may be removed from the photoconductive layer by a brush and the remaining latent image removed by exposure to light. Reference has been directed by the Comptroller to Specification 966, 694.
