Definitions

• the present invention relates to a process for dyeing with anionic dyes to produce reservation or ilulticolor effects.
• the reservation agent can first be fixed and then colored further.
• dyeing can be carried out in the presence or absence of reservation agents. If these contain reactive groups, larger amounts of them are necessary after the wet-on-wet process; if only fiber-affine agents are used, a satisfactory reserve (or multicolor effect) is generally not possible.
