The present invention relates to curable coatings comprising oligomeric condensation products of aromatic tri- or tetracarboxylic acids and dihydroxyalkyl (meth)acrylates.

Curable coatings of oligomeric condensation products

Monomers with cyclic carbonate groups of the formula I are suitable for the production of photosensitive recording materials, for example for the production of offset printing plates ##STR1## in which A means an (n+m)-valent hydrocarbon residue with 3 to 30 C atoms, which may be OH-substituted and may contain up to 8 ether bridges,

Monomers with cyclic carbonate groups

A formulation for use as a dental adhesive in the treatment of the hard tooth substance, to provide enhanced bonding between dental restoration material and the enamel and dentine of the tooth. The formulation contains glycerol di(meth)acrylate, volatile solvent, photo-initiator and, optionally, usual additives and fillers.

Dental adhesives

Polymerizable aromatic carboxylic acids and carboxylic acid anhydrides with cyclic carbonate groups which are useful for improving adhesion of synthetic dental filling materials.

Polymerizable aromatic carboxylic acids and carboxylic acid anhydrides

The invention relates to urethane acrylates and urethane methacrylates containing cyclic carbonate groups, and use thereof in dental materials and lithographic plates.

Urethane (meth) acrylates containing cyclic carbonate groups

A condensation product of a hydroxy(meth)acrylate compound corresponding to the formula ##STR1## in which R.sub.1 is hydrogen or methyl, A is a trivalent aliphatic residue with 3 to 15 C-atoms which is unsubstituted or substituted with OH groups and optionally contains up to 5 ether bridges, and an aromatic carboxylic acid anhydrides compound of the formula (II) or an aromatic carboxylic acid anhydride chloride compound of the formula (II) ##STR2## in which Ar is a benzene ring or a naphthalene ring, n is 1 or 2, and m is 0, 1 or 2. The condensation product has a molar mass of 300 and to 10,000 daltons. The condensation product is useful as an adhesive to bond dental filling materials to teeth.

Derivatives of aromatic carboxylic acids from aromatic carboxylic acid

The present invention relates to an optical solid-phase biosensor for the detection of molecules which can be labelled with a fluorescent dye for the identification of substances in solution, for which there exists a biomolecule (receptor) which specifically recognises these and is chemically bonded to the uppermost layer of one or more layers of polyions on the surface of the sensor, by measurement of the Forster transfer between another dye molecule which is bonded in one of the uppermost layers of the sensor, and the said dye molecule.

Optical solid-phase biosensor based on polyionic layers labelled with

The invention relates to diacrylates and dimethacrylates having cyclic carbonate groups, and their use in dental materials.

Di(meth)acrylates having cyclic carbonate groups

New compounds corresponding to formula (I) ##STR1## and their use as emulsifiers for aqueous emulsions and, in the case of carboxylic acid derivatives, also as reactive groups for linking to biologically active substrates. New polymers synthesized from the emulsifiers and other monomers are also claimed.

Polymerizable emulsifiers and reactive groups and polymers of

Biologically active initiators (radical chain starters) have been discovered that have the general structure of formula (I)

Biologically active initiators for radical polymerization

Specific cationic polymers having hydrophobic side chains are highly suitable as binders for pigments for the dyeing of leather.

Process for dying leather with pigments and cationic binders

The present invention relates to novel, biologically active polymers, methods for their preparation and their use for biochemical identification reactions and/or for further reaction with biologically active molecules such as, for example, proteins or nucleic acids.
