The present invention relates to compositions suitable for preparing polyurethane foams, comprising at least one OH-functional compound (OHC) obtainable by partially or fully hydrogenating a ketone aldehyde resin. The OH-functional compound contains at least one structural element of formula (1a) and optionally (1b) and / or (1c), wherein R is aromatic, 1-12 carbons having 6-14 carbon atoms (Cyclo) aliphatic having a carbon number of 1 or 2 , R 1 = H, CH 2 OH, R 2 = H or a group of the formula - (CH 2 -CH (R ') O-) y- Y = 1 to 50, k = 2 to 15, preferably 3 to 12, particularly preferably 4 to 11, and m = 0 to 13, preferably 0 to 9, And l = 0 to 2, wherein the sum of k + l + m is 5 to 15, preferably 5 to 12, and k > |
