Abstract

Farbbildner entwickelnde Beschichtung aus (a) einem Isobutyraldehyd-Phenolharz-Novolak, (b) einem festen ali­ phatischen Alkohol mit 16 bis 18 C-Atomen und gegebenen­ falls (c) für Carbondruck üblichen Wachsen. Der Anteil an (b) beträgt 10 bis 200 Gew.%, bezogen auf (a). Colorant developing coating from (a) one Isobutyraldehyde phenolic novolak, (b) a solid ali phatic alcohol with 16 to 18 carbon atoms and given if (c) waxes customary for carbon printing. The share of (b) is 10 to 200% by weight based on (a).
