Abstract (en)
[origin: EP0012623A2] A transfer material comprising a carrier sheet, one face of which is provided with a coating of a composition comprising a colourless colour former and a waxy material in which the colour former is at least substantially soluble, an oily or fatty substance forming a transfer agent or mobiliser for causing transfer of the colour former from the carrier sheet to the face of a second or acceptor sheet caused to abut there-against. By the application of mechanical pressure, the carrier sheet is pressed against such adjacent face, which latter is provided with an electron-absorbing substance, so as to form a coloured marking. The transfer agent or mobiliser is wholly or partially encapsulated in micro-capsules, the encapsulated transfer agent being provided on either one of, or both, said coated faces. Hence, at worst, the transfer agent is only minimally absorbed by the carrier sheet.
