Abstract (en)

[origin: EP0285832A2] The underside of a donor sheet (1) provided with a CB coating (2) and forming part of a multi-part form set of chemically reacting colour reaction paper is provided in a zonewise manner with an additional colour layer (4), for example based on wax. When the multi- part form set is written on in the area of the intensification zone (3) defined by the additional colour layer (4), the coloured pigments of the additional colour layer (4) are partially dissolved or dissolved by the CB substances of the CB coating and transferred to the CF coating (5) of the acceptor sheet (6). The copy in the region of the intensification zone (3) is thus intensified and especially rendered machine readable. <IMAGE>
