Copy-back (CB) coating varnishes for printing

Varnishes for printing CB coating on carbonless papers used in trade and banking.

EASY METHODS OF APPLICATION

Under the pressure of a pen or a pencil, the pigment contained in microcapsules in a CB coating mixes with a developer in a copy-front (CF) layer, colouring the outprint in places where the pressure is exerted.

CB coating varnish is a microcapsule dispersion, easy to apply on paper, used in the production of carbonless papers.
