A feature substance is provided for securing the authenticity of documents of value, having at least one luminescent substance in particle form and nanoparticles enveloping the surfaces of the luminescent substance particles at least partially, wherein the properties of the feature substance result from the interaction of the properties of the luminescent substance and of the nanoparticles. The invention furthermore relates to a method for producing the feature substance, a method for securing the authenticity of a security element or document of value using a feature substance, as well as security elements and documents of value with authenticity features on the basis of the feature substance.

Securing the authenticity of value documents by means of characteristic substances

The present invention relates to a process for the preparation of 4-aminobenzoamidine (4-AMBA) salts of general formula (I) preferably the salts thereof with hydrochloric or hydrobromic acid, particularly preferred the dichloride salt.

Process for the manufacture of 4-aminobenzoamidine dihydrochloride

This invention relates to a novel method for the preparation of 3-oxo-tetrahydrofuran comprising oxidizing 3-hydroxy-tetrahydrofuran in the presence of a catalytic amount of 2,2,6,6-tetramethyl-piperidine-N-oxyl (TEMPO) with trichloroisocyanuric acid.

Process for the manufacture of 3-oxo-tetrahydrofuran

The present invention is directed to an efficient process for the manufacture of (E)-4-N,N-dialkylamino crotonic acid in HX salt form of formula I wherein Rand Rindependently denote C-alkyl groups and Xdenotes an acid anion, such as the chloride, bromide, tosylate, mesylate or trifluoroacetate anion, with high quality, and a process for synthesis of EGFR tyrosine kinase inhibitors with heterocyclic quinazoline, quinoline or pyrimidopyrimidine core structure, using the acid addition salt I and activated derivatives thereof as intermediates.

[object Object]

A sheet-shaped document of value (BN) has luminescent feature substances (). Preferably, one luminescent feature substance is present over the entire sheet-shaped document and has a low concentration, whereas a second luminescent feature substance is present at certain partial areas and has a higher concentration.

Value document, production and verification of value documents

The invention relates to a process for preparing the compound of formula 1 a valuable intermediate product in the synthesis of the pharmaceutical active substance dabigatran etexilate.

Method for producing an intermediate product of dabigatran etexilate

The invention relates to a process for the synthesis of the diamine of formula (1) an important intermediate in the synthesis of dabiagtran etexilate. 

Process for the manufacture of an intermediate in the synthesis of dabigatran

The invention relates to a printed value document having at least one luminescent substance.

Valuable document

The present invention relates to a data carrier which contains a novel pigment composition which is preferably applied to the data carrier in the form of a coding. The pigment composition comprises a dye and a solid resin. The dye is bound in the solid resin. The resin is produced as the reaction product obtained from an oligomerized polyisocyanate and a mixture of polyfunctional compounds with active hydrogen.
