PCT No. PCT/EP91/01869 Sec. 371 Date Apr. 8, 1993 Sec. 102(e) Date Apr. 8, 1993 PCT Filed Sep. 30, 1991 PCT Pub. No. WO92/06240 PCT Pub. Date Apr. 16, 1992.The invention relates to the use of compounds containing polyether chains prepared by reaction of epoxidized C10-22 carboxylic acid derivatives with polyalkylene glycols having average molecular weights of 100 to 2,000 and/or certain alkoxylated aliphatic compounds for the removal of printing inks from printed wastepaper and/or paper circuit waters.
