COLORED SUPERABSORBERS

摘要

The invention relates to water-absorbent polymer structures containing 0.001 to 10 percent by weight of a coloring agent, the percentage being in relation to the total weight of the water-absorbent polymer structures. The inventive water-absorbent polymer structure is characterized by an L value of less than 90 according to the L,a,b color system, said L value being determined using a test method that is described herein, or the coloring agent is homogeneously distributed inside the water-absorbent polymer structure. The invention also relates to a method for producing water-absorbent polymer structures, the polymer structures obtained by means of said method, a compound containing water-absorbent polymer structures and a substrate, a method for producing a compound, a compound obtained with the aid of said method, chemical products containing water-absorbent polymer structures or a compound, and the use of water-absorbent polymer structures or a compound in chemical products.
