Laminates of a thickness of 0.2 mm to 20 mm consisting of

Laminates comprising a colored layer and thermoplastic layers having

High-temperature-resistant, flexible screen printing inks containing as binder a thermoplastic aromatic polycarbonate with a molecular weight M.sub.w (weight average) of at least 10,000 which contains bifunctional carbonate structural units corresponding to formula (I): ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent hydrogen, halogen, C.sub.1-8 alkyl, C.sub.5-6 cycloalkyl, C.sub.6-10 aralkyl, m is an integer of 4 to 7 R.sup.3 and R.sup.4 may be individually selected for each X and, independently of one another, represent hydrogen or C.sub.1-6 alkyl and X represents carbon with the proviso that, at least one atom X, R.sup.3 and R.sup.4 are both alkyl, and halogen-free solvents or solvent mixtures.

Screen printing ink containing polycarbonate binder

The production of multi-layer mouldings (17) from a sheet (6) injection-moulded behind with a resin can be simplified by the sheet (6) being deformed in an injection mould by means of a fluid pressure medium, in particular nitrogen, at at least 20 bar and the deformed sheet (6) injection-moulded behind with resin directly thereafter in this injection mould, a pressure keeping the deformed sheet (6) in position being maintained during the injection-moulding behind.

Process for producing multi-layer mouldings

Injection-moulded printed circuit boards which have been obtained by injection-moulding thermoplastic materials onto the back of flexible circuits are of a particularly high quality if the conductor tracks have been produced on the flexible carriers employed by direct additive or semiadditive metallisation.

Method of making injection-moulded printed circuit boards

Cold-stretchable sheet material is isostatically formed at an operating temperature beneath the softening temperature of the sheet material by means of a fluid pressure medium at a pressure of more than 20 bars so as to produce a deep-drawn formed plastics piece. Forming may take place abruptly. The sheet to be formed may be provided with a coating such as an ink imprint. The resulting thin-walled deep-drawn piece may be backed and reinforced by injecting further plastics material.

Apparatus for producing a deep-drawn formed plastic piece

The invention relates to new injection-moulded articles made from metal/plastic composite systems containing a polyurethane adhesive (intermediate) layer, and a process for the preparation thereof.

Injection-moulded article and process for the production thereof

A method of manufacturing a deep-drawn formed plastic piece comprises providing a cold-stretchable sheet material with a coating selected from a group of an ink film, an ink imprint, a vacuum evaporated metallic thin film, and an electrically conductive varnish film. The coated sheet is heated with a fluid pressure medium which has a fluid medium pressure of more than 20 bars, and at an operating temperature lower than the softening temperature of the sheet material, in order to deform the sheet material isostatically to obtain the deep-drawn formed coated plastic piece.

Method of producing a deep-drawn formed plastic piece

A process for the production of optically isotropic extrusion films is disclosed. Accordingly in a first process step a thermoplsatic resin is extruded to form a film having a thickness below 600 .mu.m. The second process step entails

The positive characteristics of loudspeaker diaphragms are improved by the use of a thermoplastic polyurethane sheet with a thickness of 0.06 to 0.8 mm at least for the moving part (1).

Diaphragm for loudspeaker

A 0.3 to 2 mm thick multilayer composite material comprising the following layers:

Multilayer composite material

This invention relates to multilayer films composed of thermoplastic films, tough elastic polyurethane films and optionally a sealing layer and to the use of these multilayer films for the manufacture of crash pad films, i.e. as outer skin for automobile dash boards.

Multilayer films from the use in crash pads

An invention relates to new injection-moulded articles made from metal/plastic composite systems containing a polyurethane adhesive (intermediate) layer, and a process for the preparation thereof.

Injection-moulded article and a process for the production thereof

Metal-plastic laminates are prepared by coating a metal component with a polyurethane adhesion promoter in dissolved or dispersed form, drying the liquid phase and coating with the melt of a thermoplastic by the extrusion coating process.

Process for the preparation of a metal-plastic laminate

The invention relates to laminates of five or six components and to their use for the production of skis, surfboards and furniture components.

Laminates

A layer (2) of a substance of high refractive index having an optical thickness of ##EQU1## and a layer (3) of a substance of low refractive index having an optical thickness of ##EQU2## as well as a layer (4) of a substance of high refractive index having an optical thickness of ##EQU3## and a layer (5) of a substance of low refractive index having an optical thickness of ##EQU4## are arranged as an antireflection coating on a transparent covering (1) of display devices, the wavelengths .lambda.1 and .lambda.2 being in a ratio of 1:1,5 to 1:3.
