Abstract:
1. A formulation comprising at least one granulate containing a) from 5 to 20% by weight of at least one water-soluble phthalocyanine compound, based on the total weight of the granulate, b) from 12 to 55% by weight of at least one anionic dispersing agent and/or at least one water-soluble organic polymer, based on the total weight of the granulate, c) from 25 to 70% by weight of at least one inorganic salt and/or at least one low-molecular-weight organic acid or a salt thereof, based on the total weight of the granulate, d) from 0 to 10% by weight of at least one further additive, based on the total weight of the granulate, and e) from 3 to 15% by weight water, based on the total weight of the granulate; where the phthalocyanine compound is of formula (1a) wherein PC is the phthalocyanine ring system; Me is Zn; Fe(II); Ca; Mg; Na; K; A Z q is 0, 1 or 2; r is from 1 to 4; Q wherein R X X and, in the case where R Y t is 0 or 1; in which above formulae, R R R R R u is from 1 to 6; A B A and s in the case of monovalent anions A and wherein the phthalocyanine ring system may also contain further solubility-imparting groups and where the inorganic salts are selected from the group consisting of alkali metal salts of carbonates, hydrogen carbonates, phosphates, polyphosphates, sulfates, silicates, halides and pyrophosphates, and where the low-molecular-weight organic acids and salts thereof are selected from the group consisting of oxalic acid, tartaric acid, acetic acid, propionic acid, succinic acid, maleic acid, citric acid, formic acid, gluconic acid, p-toluenesulfonic acid, terephthalic acid, benzoic acid, phthalic acid, acrylic acid, and salts thereof.
