Abstract: A colorant catcher material includes a) a substrate and b) a colorant-catching additive. The colorant-catching additive is selected from the group consisting of polyvinylamines in form of homopolymers, copolymers and/or partial salts thereof, polyethylenimines in form of homopolymers, copolymers and/or partial salts thereof, and mixture thereof. The colorant-catching additive is fixed on the substrate by c) a fixing agent selected from the group consisting of dialdehydes with the carbon number of from 2 to 8. Also disclosed is a method for preparing the colorant catcher material and use of the same for catching colorants or removing dirt in an aqueous medium, particularly a laundry washing solution.
