    Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane usable as a hair setting agent, having excellently cleaning down properties (redispersibility), especially for a hair treatment composition. SOLUTION: This cross-linked water-soluble or water-dispersible polyurethane or its salt comprises (A) at least one water-soluble or water-dispersible polyurethane polymer containing a terminal isocyanate group composed of (a) at least one compound containing two active hydrogen atoms in one molecule and having 56-300 molecular weight, (b) at least one polymer containing two active hydrogen atoms in one molecule, (c) at least one compound containing at least two active hydrogen atoms in one molecule and at least one ionogen group or ionic group and (d) at least one diisocyanate and (B) at least one polymer containing a group reactive to an isocyanate group, selected from a hydroxy group, a primary and a secondary amino groups and/or carboxy group.

    Abstract: The invention relates to the use of reactive dyes for dyeing hair. Said reactive dyes are of formula (I), wherein a represents 1 or 2, b represents 0 or 1, Y represents vinyl or a radical of formula C2H4Q, Q being a group which can be split off in alkaline reaction conditions, L represents a direct bond or a binding link of formula CO-NH-M which can be interrupted by 1 or 2 non-adjacent oxygen atoms, imino or C1-C4 alkylimino groups, M being C2-C6 alkylene, A represents hydroxysulfonyl or a radical of formula SO2Y, A represents hydrogen, hydroxysulfonyl, methoxy, chlorine, bromine or carboxyl, W represents 1) the radical of a coupling constituent, of a monoazo dye or additionally, when b=0, of a disazo dye, which can carry other reactive groups, or 2) the radical of a chromophore which optionally has other reactive groups, and L and L each represent a binding link. The invention also represents a method for dyeing hair, and cosmetic preparations for dyeing hair.
