    摘要: Sensitization of silver halide emulsions by merocyanines and cationic cyanines and the stability of this sensitization is improved by addition of heterocyclically substituted thioureas of the formula ##EQU1## wherein R.sup.1 is alkyl, alkenyl or arylR.sup.2 is alkyl, cycloalkyl or aryln is 0 or 1, andZ completes a 5- or 6-membered heterocyclic group, preferably one which also contains a sulfur atom.

    摘要: Non-aqueous inks having an electric conductivity of at least 10.sup.-4 Ohm.sup.-1 cm.sup.-1, a viscosity of at most 5 cP at 20.degree. C. and in which the liquid medium consists completely or predominantly of one or more solvents having each an evaporation index of less than 11 are most useful for the ink-jet recording process in which a jet of ink is ejected from a nozzle by application of pressure and after its breaking up into droplets is modulated according to the information to be recorded. Such inks are particularly useful for writing on non-absorbent surfaces.
