| abstract | A copying sheet has on one face a coating contg. a magnesium-aluminium silicate (e.g. attpulgite, bentonite) and a transfer sheet carrying an image formed by a pigment paste including a leuco-auramine and an alcohol is pressed against thio surface whereby the image is transferred to the copy sheet. The reverse face of the copy sheet is coated with a material which does not react chemically with leucoauramine, e.g. a slightly alkaline dispersion of BaSO4 or ZnO in a synthetic resin (e.g. amido, polyvinyl chloride (polyvinyl acetate copolymer) or carboxymethyl cellulose. The reverse face may be coloured to ensure that the paper is fed into a copying machine the correct way round. Accidental marking of the reverse face of the copy sheet is prevented, since any stray pigment cannot adhere to the coating on the reverse face. |
