description This invention relates to a process for dyeing wood with a liquid dyestuff preparation containing (a) 5 to 30% by weight of a dyestuff of the formula (I) 1  wherein n 1 and n 2 denote the number 1 or 0, X represents N or CH, Ct + represents a cation, A, B, G, and D are independently a polyvalent heterocyclic or aromatic radical in which the -(CO)n 1 -O- or -O- are ortho to the respective -N N- or -N X-, and (b) 15 to 90% by weight of an alkoxyalcohol of the formula (II) R-O-(-Z-O-) n3 -H  (II)  wherein R denotes a straight-chain or branched C 1 -C 4 -alkyl, Z denotes a straight-chain or branched C 2 -C 3 -alkylene, and n 3 represents 1, 2, or 3, and (c) 5 to 75% by weight of water.
