Abstract
The optically clear compositions comprising (A) an organopolysiloxane which contains at least one monovalent SiC-bonded radical with primary, secondary and/or tertiary amino groups, (B) 0.01 to 1 part by weight per 100 parts by weight of organopolysiloxane (A) of a group of compounds consisting of water, methanol and ethanol and (C) 0.05 to 20 parts by weight of a solubilizing agent per 100 parts by weight of organopolysiloxane (A), chosen from a group consisting of (C1) C.sub.1 - to C.sub.19 -carboxylic acid C.sub.1 - to C.sub.12 -alkyl esters and -glycol esters, (C2) C.sub.3 - to C.sub.20 -alkanols and C.sub.3 - to C.sub.20 -alkanol-C.sub.1 - to C.sub.12 -alkoxylates and (C3) organosilicon compounds containing glycoside radicals.
