Abstract

An eraser composition comprising at least one elastomer thermoplastic binder which is a block copolymer of an elastomeric, thermoplastic polyester having a soft, amorphous phase and a hard, crystalline phase, and fillers, optionally plasticisers and/or further additives and triethanolamine.

Description

Die Erfindung betrifft einen Radierer nach dem Haupt­ patent (P 36 02 794.4) mit den Merkmalen des Oberbegriffs des Hauptanspruchs.The invention relates to an eraser after the head patent (P 36 02 794.4) with the features of the generic term of the main claim.

Unter den im Hauptpatent beschriebenen Radierern sind bereits Zusammensetzungen beschrieben, die neben einem elastomeren, thermoplastischen Polyester mit einer weichen amorphen und einer harten kristallinen Phase (im folgenden Co-Polyester), als Weichmacher Dibutyl­ phthalat, Diisobutylphthalat, Chlorparaffin oder Epoxy­ weichmacher, als Füllstoffe Calciumcarbonat oder Bimsmehl, sowie Factis, enthalten.Among the erasers described in the main patent are already described compositions that in addition to a elastomeric, thermoplastic polyester with a soft amorphous and a hard crystalline phase (hereinafter co-polyester), as a plasticizer dibutyl phthalate, diisobutyl phthalate, chlorinated paraffin or epoxy plasticizers, as fillers calcium carbonate or pumice flour, as well as factis.

Die DE-AS 22 10 684 lehrt, Radierern mit einem Anteil gelierender Weichmacher und Polyvinylchlorid, nicht flüchtiges Tuschelösungsmittel, z. B. Triäthanolamin, zuzusetzen.DE-AS 22 10 684 teaches erasers with a share gelling plasticizer and polyvinyl chloride, not volatile ink solvent, e.g. B. triethanolamine, to add.

Es hat sich aber erwiesen, daß gerade das als Tusche­ lösungsmittel besonders wirksame Triäthanolamin in solchen PVC-haltigen Radierern zu negativen Erscheinungen, wie Migration, Vergilbung oder zur Bildung toxischer Reaktions­ produkte bei der Verarbeitung führen kann.However, it has been shown that this is just an ink particularly effective triethanolamine in such PVC-containing erasers like negative appearances Migration, yellowing or the formation of a toxic reaction products during processing.

Demgegenüber hat sich gezeigt, daß sich Triäthanolamin in den erfindungsgemäßen Radierern nach dem Hauptpatent hervorragend ohne unerwünschte Nebenwirkungen einsetzen läßt. Dabei wirkt Triäthanolamin sowohl als Tuschelösungs­ mittel, als auch als Weichmacher. In contrast, it has been shown that triethanolamine in the erasers according to the invention according to the main patent excellent use without unwanted side effects leaves. Triethanolamine acts both as an ink solution medium, as well as a plasticizer.  

An Hand einiger Ausführungsbeispiele soll die Erfindung nachfolgend näher beschrieben werden:The invention is intended to be illustrated using a few exemplary embodiments are described in more detail below:
