- EP-A 572 256 polyester with organic diisocyanates extended to the end product.
- the use of thermoplastic polyester urethanes as compostable plastics is described in EP-A 593 975.
- Thermoplastic processable and biodegradable polyester amides are the subject of EP-A 641 917
- thermoplastic polyurethane filaments are described in DE-PS 4 319 439.

These polyurethanes are reaction products of diisocyanates and diols which are used for the purpose of hydrophilizing the The end product also contains built-in residues of diaminosulfonates and, where appropriate, ethylene oxide group-containing polyethers.
- hydrophilic polyurethanes can be used as a lacquer for coating any substrates, as an adhesive and / or as a binder for cellulose for the production of nonwovens made of cotton and / or hemp or linen, as a polymeric binder Wood, wood dust or wood shavings, as films in composite materials for the production of biodegradable packaging, for the production of hygiene articles such as baby diapers, as seed dressings for fixing active substances as slow release formulations, as binders for the production of Pfla Net pots can be used as paper coatings and for the mass sizing of paper, for the production of sausage casings and for the production of cosmetic compositions

Staining can be carried out in a known manner in the padding and exhausting process According to a special embodiment, the mixtures of A and B can be used together with pigment for the dyeing of textiles and leather in an aqueous medium
- the wash fastness of dyeings and prints can be checked using the burst wash test.
- Abrasion can serve as a measure of the degree of crosslinking of the binder
- a sample (approx. 10 x 20 cm) of the dyed and printed fabric is then fixed in a mixture
- the printing pastes were worked on release paper and films were made from them.
- the films were subjected to the following composting test:
- the films to be tested were first dried to constant weight at 80 ° C. and then clamped in 6 ⁇ 6 cm slide frames.
- Compost from a composting plant was filled 2 cm high in plastic trays and the films were placed in it.
- the filled boxes were incubated in an incubator for 4 weeks at 60 ° C. Water losses were determined and compensated for by weight loss.
- the pH of the compost was measured once a week during the incubation. After 4 weeks each batch was stopped, the films removed, cleaned, dried to constant weight at 80 ° C. and photographically immediately after drying, the weight loss of the films was determined by weighing again
- the compost was dried at 105 ° C., the evaporated water was then replaced by 1% HgC ⁇ solution.
- the films for the poisoned control were placed in the HgCl 2 solution before being introduced into the compost mixture , dried and then placed in the poisoned compost.
- the control batch was incubated in exactly the same way as the other batches
- a film was said to be degradable if it disappeared completely in the microbially active batches and the cellulose film used in a parallel test and was retained in the poisoned control
- the coated products had the required fastness properties in flexometer and adhesion; the products proved to be biodegradable.
- Printing pastes 23 (prior art) and 24 (paste according to the invention) were subjected to the biodegradability test for five days four hours after production (BOD-5, method: LCK 55 cuvette test from Lange).
- the printing paste 24 showed the expected high degradability rate with a comparable application properties.
