| titleOfInvention | Polyurethane dispersions |
| abstract | The present invention relates to aqueous dispersions containing at least one polyurethane and at least one compound with a biocidal action, the at least one compound with a biocidal action containing at least one peroxide group and being present in a quantity of between 0.01 and 1,000 mmol/kg, in relation to the total aqueous dispersion, and relates to a process for preparing a biocide-free aqueous polyurethane dispersion, said process comprising at least the steps: (A) preparing an aqueous solution containing at least one polyurethane and at least one compound with a biocidal action, the at least one compound with a biocidal action containing at least one peroxide group and being present in a quantity of between 0.01 and 1,000 mmol/kg, in relation to the total aqueous dispersion; and (B) treating the aqueous dispersion from step (A) with at least one compound with an anti-oxidative action, in order to obtain the biocide-free aqueous polyurethane dispersion, and in addition relates to the use of at least one compound with an anti-oxidative action for treating an aqueous dispersion containing at least one polyurethane and at least one compound with a biocidal action, the at least one compound with a biocidal action containing at least one peroxide group and being present in a quantity of between 0.01 and 1,000 mmol/kg, in relation to the total aqueous dispersion. |
