Process for the production of leather using products obtainable by reacting (A) at least one cyclic organic carbonate with (B) at least one compound having at least two nucleophilic groups per molecule, selected from sulfonic acid, hydroxyl, primary or secondary amino or mercapto groups.

Leather production method and products suited thereof

The invention relates to a method for vulcanizing caoutchouc or latex by adding a mixture M which contains a component a) from a1) 20 to 96% by weight of sulfur, a2) 4 to 80% by weight of a complexing agent, and optionally other additives b) to caoutchouc or latex and then vulcanizing the mixture. The inventive method is characterized in that the average particle size of the primary particles of component a) ranges from 0.05 to 20 &#x3bc;m.

Phthalocyanine and use of phthalocyanine as a marking agent

Use of compounds from the class of the phthalocyanines, naphthalocyanines, nickel dithiolene complexes, aminium compounds of aromatic amines, methine dyes or azulenesquaric acid dyes which have their absorption maximum in the range from 600 to 1,200 nm and/or a fluorescence maximum in the range from 620 to 1,200 nm, as markers for liquids, a process for detecting markers in liquids, and a detector suitable for this purpose.

Use of compounds which absorb and/or fluoresce in the IR region as

Compounds of the general formula I ##STR1## where the A radicals are, independently of one another, ##STR2## where the rings B and C can also, independently of one another, be substituted by C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, nitro, hydroxysulfonyl, benzoyl or a fused-on benzo ring,
