Claim 12:
13. A method of making a single-component sealant or adhesive composition, comprising adding an epoxy- or carbodiimide-functional cross-linker C with an amount of between 0.5 and 5 wt.-%, based on the total composition, to an aqueous polymer dispersion having a pH of 7-12 and comprising at least one water-dispersed polymer P having a median particle size D50 of less than 150 nm, wherein the at least one water-dispersed polymer P is comprised in the composition with an amount of at least 45 wt.-%, based on the total composition, to improve the transparency and water-resistance of the composition in the curing or cured state when in contact with water.
