Abstract
Abstract Oxyalkylated 1,3-bis-aryl-glycerol ethers of the formula <IMAGE> (I) where R and R1 are aromatic substituents, R2 is -CH3 or -C2H5, R3 is -H or -CH3, n is from 0 to 10 and m is from 8 to 50. The compounds of the formula I are used as emulsifiers, preferably in the preparation of print pastes.
