ABSTRACT:
Coating methods and compositions for products and transfer media, such as carbon papers, in which a preliminary coating of liquid-dispersed colorant, such as carbon black, is applied at a first stage followed by a transfer overcoating at a second stage. The multistage coating procedure affords the threefold benefits of (1) improved image transfer properties in the product; (2) a reduced tendency of the product to smudge; and (3) less than the conventional amount of transfer materials for a specified result being required.
