The present invention relates to a process for the production of wood-base materials which have at least one thin veneer layer adhesively bonded over the surface to a substrate or to further veneer layers, which process comprises the following steps:

Method for producing wood-base materials

The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0&#xd7;10, and to a process for the preparation thereof.

Lignocelluosic material which is low in formaldehyde and method for the production thereof

Use of copolymers containing sulfonic acid groups which comprise  

Use of copolymers containing sulfonic acid groups, as an additive in detergents and cleansers

A cleaner composition which comprises at least one surfactant, at least one builder and at least one nitrogen-containing polymer is described. The nitrogen-containing polymer is, for example, an alkoxylated polyvinylamine, an alkoxylated, acylated or alkylated polyaminoamide or a polyurethane-urea with tertiary amino groups. The nitrogen-containing polymers facilitate soil release.

Cleaning agent composition comprising polymers containing nitrogen

Solvent-free pigmented formulation

Dispersant

Continuous recovery of raw materials from coated films and apparatus for this purpose and film material recovered therewith. Large amounts of coated films can be fed to a continuous recycling process in which any pigments present in the coating and the substrate material are recovered. The treatment is carried out at room temperature in an alkaline medium consisting of soft soap, organic solvent and/or water, with or without the use of a catalyst. The solvent is recycled. After the first treatment stage, the film shreds can be treated in a second stage with a solvent/water mixture similarly to the first stage, and thorough final washing in a water or solvent circulation is effected in a third stage. The recovered film shreds are dried, pressed, milled and brought to the desired shape in a plastics agglomerator, and the recovered pigments are dried under reduced pressure (FIG.,). The process and apparatus can be used with advantage for any type of substrate or printed media, for example for magnetic substrates, photographic substrates, printing plates, pigment-free substrates.

Continuous process for recovering raw materials from coated foils, device for carrying out this process and foil materials recovered thereby

The thermoplastic, isocyanate-free polyurethane which contains acidic groups, is soluble in tetrahydrofuran, has a molecular weight of from 15,000 to 70,000 and is composed of
