Processes and compositions for printing substrates. A printing paste containing a matrix-forming precondensate containing polyorganosiloxanes obtained by a sol-gel process and at least one coloring, luminescent, conductive and/or catalytically active filler is applied imagewise to the substrate and is densified by heat treatment at a temperature below the glass transition temperature of the matrix being formed. The processes and printing pastes are suitable, for example, for the production of conductor tracks and decorative patterns.
摘要:
A description is given of coated inorganic pigments comprising an organic pigment which has a coating, prepared by the sol-gel process from glass-forming components and densified to form a xerogel or glass, having a layer thickness of at least 0.8 .mu.m. These pigments are prepared by spray drying a sol-pigment dispersion, followed if desired by thermal densification of the xerogel layer to form a glass layer. The coated pigments are suitable for producing enamels and moldings.

A process for providing a substrate having a metal, glass or ceramic surface with a vitreous layer comprising an interference pigment. The process comprises comminuting an interference pigment having at least one dielectric interference layer by a wet grinding process; dispersing the comminuted interference pigment into a silicate-containing suspension to obtain a coating composition; applying the coating composition to the surface by a wet coating process; and densifying the coating composition at a temperature of not more than 650° C.

Magnetic particles with an outer glass surface being essentially poreless or having pores of a diameter of less then 10 nm as well as ferromagnetic particles with a glass surface are preferentially useful for the isolation of biological material from samples. They provide a quick and reliable purification.

Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment.The inventive coating is suitable for optical layers, particularly on translucent substrates. Examples of adequate uses include antireflection layers and interference layer assemblies.

摘要:
Magnetic particles are prepared containing a magnetic core coated with a glass layer having a substantially pore-free class surface or having pores with a diameter offices than 10 nm. The particles are used for separating biological material such as nucleic acids. A preferred process of preparing the particles is by forming a mixture of magnetic cores with a sol formed from an alcohol and a metal alkoxide, spray-drying the mixture to coat the cores with a layer of gelled sol, and heating the coated cores to obtain the magnetic glass particles. Preferably, the particles have an average particle size of less than 100 μm. The magnetic core may be a composite material containing a mica core and magnetite particles immobilized on the mica core, and the glass layer may contain boron oxide. Magnetic core materials include magnetite (Fe3O4) and Fe2O3.
