Abstract
When a transferred image is formed on a plain paper by the use of a colorless backcarbon paper coated with an alcohol-based flexographic ink composed essentially of (A) microcapsules whose core substance is an oil droplet containing an electron-donating organic color former, (B) microcapsules whose core substance is an oil droplet containing an electron-accepting organic color developer, (C) a binder resin and (D) a solvent composed mainly of a lower alcohol of 1 to 3 carbon atoms, the density of the transferred image is improved by adding an appropriate amount of a wax to the core substance(s) of either or both of the above microcapsules (A) and (B).
