Abstract

A composition used as an intermediate layer in " carbon " paper (see Division D2) comprises: carnauba wax, ceresin, lavolin and mineral oil. In another example, the transfer layer is made from a composition comprising: ouricoury wax, microcrystalline wax, oleic acid, potassium hydroxide, glycerine, carbon black and water.ALSO:Compositions used to form the transfer layers of "carbon" papers (see Division D2) comprise: (Example 1) ethylcellulose, lard oil, oleic acid, carbon black, nigrosine dye and toluene; (Example 2) vinyl chloride-vinyl acetate copolymer, lard oil, oleic acid, carbon black, ethyl acetate and toluene; and (Example 3) lanolin, polybutene resin, butyl rubber, mineral oil, graphite, naphtha and toluene.ALSO:An original image for a thermographic copying process (see Division G2) is produced by means of a transfer sheet and comprises and infrared radiation-absorbing imaging material together with a film-forming or soap binder material which does not melt or spread out at the temperatures generated in the original image by the radiation absorbed in the copying process. The film-forming binder may be a cellulose derivative or a polyvinyl resin. In the examples, transfer layers for forming original images comprise: (1) Ethylcellulose, lard oil, oleic acid, carbon black and nigrosine dye; (2) vinyl chloride-vinyl acetate copolymer, lard oil, oleic acid and carbon black; (3) lanolin, polybutene, butyl rubber, mineral oil and graphite; and (4) ouricury wax, microcrystalline wax, oleic acid, potassium hydroxide, glycerine and carbon black; and are applied to a flexible foundation that may be paper (Examples 1 and 4) or polyethylene terephthalate (Example 2) in solution or suspension in an organic solvent (Examples 1 to 3) or water (Example 4) and the solvent then evaporated. In Example 3, the flexible foundation is first coated with a hot melt comprising carnauba wax, ceresin, lanolin and mineral oil which is transferred with the transfer layer to form a heat-softenable sealing layer over the transferred image.
