| 摘要 |
The invention relates to flexible, flat substrates with a flexible, abrasive surface which comprise 0.1 to 90% by weight of a mixture, based on the uncoated substrate, which comprise the condensation product of 99.985 to 20% by weight of at least one precondensate of a heat-curable resin, 0.005 to 10% by weight of a polymeric thickener selected from the group consisting of biopolymers, associative thickeners and/or completely synthetic thickeners, 0.01 to 10% by weight of a curing agent, 0 to 10% by weight of surface-active substances or surfactants, 0 to 15% by weight of active ingredients and effect substances and 0 to 75% by weight of water, where the mixture comprises 10 to 70% by weight of one or more binders, from the group of polyacrylates, polymethacrylates, polyacrylonitriles, copolymers of acrylic acid esters and acrylonitrile, styrene and acrylonitrile, acrylic acid esters and styrene and acrylonitrile, acrylonitrile and butadiene and styrene, polyurethanes, melamine-formaldehyde resins, phenol-formaldehyde resins, urea-formaldehyde resins, melamine-urea-formaldehyde resins, melamine-urea-phenol-formaldehyde resins, urea-glyoxal resins, or mixtures thereof. |
