Gegenstand, der Erfindung sind Pigmentpasten und deren Verwendung zum Einfärben von Zweikomponentenpolyester-Polyurethan-Textilbeschichtungsmassen. The invention relates to pigment pastes and their use for coloring two-component polyester-polyurethane textile coating compounds.
Es ist bekannt, Textilbeschichtungsmassen auf Basis von Polyesterpolyurethanen mit Pigmentpasten einzufärben. Die dabei verwendeten Pigmentpasten enthielten meist neben Pigment und üblichen Zusätzen wie Lösungsmitteln Bindemittel auf Basis von Polyvinylchlorid-Polyvinylalkohol, gegebenenfalls unter Zusatz von üblichen Weichmachern auf Basis von Alkydharzen oder Epoxydharzen oder übliche Polymerweichmacher.It is known that textile coating compositions based on polyester polyurethanes to be colored with pigment pastes. The pigment pastes used mostly contained pigment and customary additives such as solvents binders based on polyvinyl chloride-polyvinyl alcohol, optionally under Addition of customary plasticizers based on alkyd resins or epoxy resins or customary polymer plasticizers.
Diese Pigmentpräparationen beeinflussen die Eigenschaften der Beschichtungen ungünstig, insbesondere den trocknen textlien Griff, den Glanz, die Hydrolysebeständigkeit oder die Knickfestigkeit. These pigment preparations have an unfavorable effect on the properties of the coatings, especially on dry textiles Handle, gloss, hydrolysis resistance or kink resistance.
Man hat diese Nachteile zu vermeiden versucht, indem man als Bindemittel für die Pigmentpasten dasjenige Polyesterpolyurethan verwendete, das auch für die Beschichtung verwendet wurde. Zwar konnten damit die oben genannten Nachteile vermieden werden, nachteilig ist jedoch, daß man für jede spezielle Beschichtungsmasse ein genau abgestimmtes Pigmentpasten-Sortiment bereitstellen muß, da Polyesterpolyurethane untereinander oder mit ihren Lösungen in beispielsweise Dimethylformamid nur bedingt verträglich sind.Attempts have been made to avoid these disadvantages by using the polyester polyurethane as the binder for the pigment pastes used, which was also used for the coating. It is true that the disadvantages mentioned above could be avoided in this way However, it is disadvantageous that a precisely matched range of pigment pastes is required for each special coating material must provide, as polyester polyurethanes with one another or with their solutions in, for example, dimethylformamide only are conditionally compatible.
