ABSTRACT:
A carbonless copying system which enables the formation of images that are capable of being detected by an optical character recognition (OCR) device. A phenolic resin or reactive clay image-forming component is applied as a CF coating on a recording substrate. A first complementary image-forming component which is a microencapsulated dye precursor that is capable of forming a colored image when contacting the CF coating is applied as a CB coating to a transfer substrate. A second complementary image-forming component, which is a microencapsulated dye precursor capable of forming a colored image when contacting the CF coating that is detectable by an OCR device, is applied as a CB coating to selected portions of the transfer substrate. The dye precursor capsules, upon rupture by application of pressure, release the dye precursor which contacts and reacts with the phenolic resin or reactive clay to form colored images, with those images formed from second complementary image-forming component being capable of detection by an OCR device. The carbonless copying system of the invention is particularly useful in credit card sales slip applications.
