    摘要: A process for purifying C.sub.8 -C.sub.16 -alkylglycosides which have been obtained by reacting lower alkylglycosides or hydroxyalkylglycosides with C.sub.8 -C.sub.16 -alcohols in the presence of an acid catalyst, by distillative removal of unconverted C.sub.8 -C.sub.16 -alcohols, wherein the distillative removal, at least of the last amounts of unconverted alcohols, is carried out in the presence of glycols whose boiling points are at most 10.degree. above, and at most 30.degree. below, those of the alcohols to be removed.

    摘要: A photopolymerizable composition for the production of water-developable printing plates and relief plates, based on a water-soluble or water-dispersible mixture, containing a photoinitiator, of(a) one or more water-soluble or water-dispersible polymers containing copolymerized N-vinylpyrrolidone units and/or one or more polymers containing vinyl alcohol units and(b) one or more olefinically unsaturated photopolymerizable monomers,which comprises, as an additive or as the sole polymer, a water-soluble modified vinyl alcohol polymer which contains from 5 to 75, especially from 10 to 60, % by weight of chemically bonded oxyethylene units. These modified vinyl alcohol polymers are in particular oxyethylated polyvinyl alcohol or hydrolyzed graft polymers of vinyl esters onto polyethylene glycols. The compositions are easier to process into printing plates and relief plates, and exhibit a long shelf life.
