ABSTRACT:
A carbonless copy system which enables the formation of a plurality of different colored images on a substrate. A phenolic resin or reactive clay image-forming component is applied as a CF coating on a recording substrate. One or more coatings of encapsulated dye precursors (complementary image-forming components) are applied to selected portions of the CF coating on the recording substrate and one or more coatings of encapsulated dye precursors are applied to selected portions of a transfer substrate. The dye precursor coatings are capable of forming different colored reaction products when coming into contact and reacting with the phenolic resin or reactive clay. Upon applying pressure to the transfer substrate, the dye precursor capsules are ruptured, releasing the dye precursor which contacts and reacts with the phenolic resin or reactive clay to form the colored reaction products.
