Abstract: The present invention relates to a dispersion comprising (A) a carrier fluid in an amount from 35 to 95 wt. %, the carrier fluid comprising: (A1) water, and (A2) at least one compound selected from the group consisting of ethanol, 1-propanol, 2-propanol, ethyl acetate, n-propyl acetate, isopropyl acetate, acetone, methyl ethyl ketone and any mixture of at least two of these compounds, whereby the amount of water (A1) relative to the carrier fluid (A) is less than 85 wt. % and the amount of water relative to the dispersion is from 1 to 30 wt. %; and (B) polymer(s) in an amount from 5 to 65 wt. %, the polymer(s) comprising: (B1) polymeric particles having a volume average particle size from 1 μm to 20 μm, whereby the polymer of the polymeric particles (B1) has a weight average molecular weight of at least 100 kDaltons and whereby the polymer of the polymeric particles (B1) is selected from the group consisting of polyurethane, polyurethane-polyacrylate hybrid and any mixture thereof; and whereby the amounts of (A) and (B) are given relative to the total amount of (A) and (B).
