Abstract: Polyfunctional alcohols with at least two alcoholic hydroxy groups are effective agents for dispelling fog and clouds. Preferred solid compounds are the so called sugar alcohols, saccharides and polyvinyl-alcohol, as liquid compounds or compounds with a low melting point alkane-diols, -triols or polyols or their reaction products with oxalkylating agents. The said compounds are sprayed into fog or clouds in finely dispersed form. They may be used, optionally together with other fog and clouds dispelling agents.

Abstract: Pigment compositions of resins and xanthene dyestuffs, which are prepared by dissolving the dyestuff salt with the addition of alkali in an organic solvent miscible with water or in an organic amine, dissolving in this solution such a resin which can be precipitated again by addition of an acid, or adding such a solution of such a resin in one of the said solvents, mixing the mixture thus obtained with an aqueous acid and recovering the pigment composition precipitated. The pigment compositions according to the invention are distinguished by an extraordinary good brilliance of the prints produced therewith. They are extremely easy to disperse in printing varnishes and therefore especially valuable in use.
