    Application:

    The substance is applied in the manufacturing of carbonless and thermal paper products, such as

    receipts, tickets, barcode labels, lottery tickets and many other applications as a black color former.

    ETAC can be applied in the conventional way as a color former by the application of an aqueous coating composition to a pre-coated base paper followed by drying and calendaring. The coating composition will also contain appropriate amounts of various additives including for example color developer and sensitizer.
