    Abstract: Oil-soluble, phenolic resin-modified natural resinic acid esters, which are able to form self-gelling mineral oil solutions and in the form of gel varnishes can advantageously be used as binder resins in printing inks for offset printing and letterpress printing, and also processes for their preparation from natural resins, phenols, aldehydes, condensation catalyst, esterifying agents and modifiers by reaction of the components at temperatures in the range from 80.degree. to 300.degree. C., individual components preferably being initially introduced and the other components being metered in, the combined use of a magnesium compound as condensation catalyst and the continuous removal of the water of reaction during the condensation reaction by azeotropic distillation with co-use of an inert organic solvent as distillative entraining agent being necessary and decisive for the self-gelling property of the process product.

    Abstract: The extruded, biaxially oriented dielectric film is composed of high-purity electrical film raw material. It is suitable as electrical insulating film in particular as a dielectric in an electrical capacitor, and exhibits improved dielectric properties for this prupose. The film comprises propylene polymers and stabilizers for the propylene polymers. The raw material of the film has an idealized thermo-oxidation temperature in the range from 260.degree. to 300.degree. C., preferably 260.degree. to 280.degree. C. The dielectric film has an idealized thermo-oxidation temperature of 250.degree. to 300.degree. C., in particular 250.degree. to 280.degree. C. The content of organic neutralizing agents, in particular calcium stearate, in the raw material is less than/equal to 100 ppm.

    Abstract: Disclosed is an opaque, biaxially stretch-oriented, polyolefinic multilayered film comprising an opaque core layer and two transparent top layers. The core layer contains a mixture of1) about 45 to 90% by weight of a thermoplastic polymer comprising propylene,2) about 5 to 25% by weight of an inert, particulate filler, and3) about 5 to 30% by weight of a hydrocarbon resin being compatible with the thermoplastic polymer and having a softening point in the range from about 100.degree. to 160.degree. C.,the percentages being each time related to the total weight of the mixture. The top layers are free from admixtures comprising particulate filler and resin. The film possesses high resistance to delamination.

    Abstract: Moldings having a thickness of 1 to 60 mm and made of flexible webs or rigid sheet of plastic are passed through a corona discharge treatment system consisting of high-voltage electrodes and a counter-electrode and a high-frequency alternating current voltage of 20 to 25 kHz and 20 to 70 kV is applied to the high-voltage electrodes by a generator. A corona discharge forms in the gap between the high-voltage electrodes and the counter-electrode. An aerosol formed by atomizing a liquid is blown into the corona discharge zone by means of an air or gas stream. The aerosol modifies the surface of the sheet-like molding in the desired manner.
