Abstract
Abstract The invention relates to colorant preparations containing the following main constituents: A) at least one dispersed (A1) or dissolved (A2) colorant; B) if a colorant corresponding to (A1) is used, a dispersing agent; C) a low-molecular polytetrahydurofurane (C1), optionally mixed with one or more difficult-to-evaporate, water-soluble or water-miscible organic solvents (C2); and D) water.
