.beta.-Hydroxyalkylpicolinium salts of the formula (I) ##STR1## wherein A, R.sup.1 to R.sup.3 and X have the meanings given in the description, which are obtained by reaction of picolines of the formula (II) ##STR2## with alkylene oxides of the formula (III) in the presence of a 1- to 3-basic acid and in water or an organic solvent as the reaction medium and are used as intermediate products for the preparation of cationic dyestuffs, and dyestuff preparations comprising such cationic dyestuffs.

Process for the preparation of beta-hydroxyalkypicolinium salts

To prevent dusting of a solid such as a crop protection agent, a pharmaceutical or a dyestuff, there is added thereto as a dustproofing agent a compound of the formula I ##STR1## in which Z represents Z.sub.1 or Z.sub.2 where

Dustproofing agents

A dye acceptor element for thermosublimation printing comprising a support and a dye acceptor layer containing a vinyl copolymer having a glass transition temperature of 50 to 100.degree. C. and a plasticizer having a molecular weight MW of 150 to 1,000 is distinguished by high color density, high sharpness, good image stability and a minimal tendency towards adhesion.

Acceptor element for thermosublimation printing

The invention relates to new cleavable surface-active silane derivatives of the formula ##STR1## in which R.sub.1, n, R.sub.2, R.sub.3, X, m and R.sub.4 have the meaning given in the description, and furthermore processes for the preparation of these silane derivatives and the use of these compounds as surfactants.

Preparation of emulsions or other multiphase formulations

In the spraying of an aqueous liquor comprising at least one of 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-pentan-3-ol and 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol, the improvement which comprises including in the liquor di-styryl-phenyl-tri-glycol ether, whereby crystallization of II and III is reduced.

Di-styrl-phenyl-triglycol ether as crystallization inhibitor

The carrier mixture contains N-alkylphthalimides and compounds of the general formula ##STR1## in which R is C.sub.1 -C.sub.7 -alkyl; phenyl, benzyl or phenylethyl, which can be substituted by C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkoxycarbonyl,

Carrier mixture for the dyeing of polyester materials:

Levelling agents for disperse dyeing of polyester: ethoxylate or

Pigment preparations which contain an organic pigment and/or carbon black and a surfactant from the sulphosuccinic acid ester and/or alkylbenzenesulphonate series and which have been dried, if appropriate after wet comminution, by spray- or freeze-drying from an aqueous medium, and the use of these preparations for pigmenting high molecular weight organic material, in particular thermoplastics.

Pigment preparations

The present invention relates to new macroemulsions which contain

Biocidal macroemulsions containing polyvinyl alcohol

Ammonium compounds of the formula ##STR1## in which R and R.sub.1 designate C.sub.1 -C.sub.21 -alkyl or C.sub.2 -C.sub.21 -alkenyl,

Ammonium compounds
