Description

Grafit enthaltende Schreibpaste für Kugelschreiber zur Erzielung verschiedener Schriftbildcharaktere Es sind Kugelschreiber bekannt, bei denen zur Erzielung eines bleistiftähnlichen Schriftbildes der Schreibpaste neben den üblichen löslichen Farbstoffen auch Grafit zugesetzt wird. Diese Paste gibt jedoch nur ein verhältnismäßig konstantes Schriftbild, das von der Art und Weise der Handhabung :durch den Benutzer mehr oder weniger abhängig ist.Writing paste containing graphite for ballpoint pens to achieve various Typeface characters There are ballpoint pens known in which to achieve a pencil-like typeface of the writing paste in addition to the usual soluble dyes graphite is also added. However, this paste only gives a relatively constant one Typeface that depends on the way of handling: by the user more or is less dependent.

Der Erfindung liegt nun die Aufgabe zugrunde, auch mit Kugelschreibern Schriftbilder zu schaffen, -die der Bleistift-Härtegradskala angepaßt werden können, so daß der Kugelschreiber nunmehr für die verschiedensten Zwecke verwendet werden kann.The invention is now based on the object, also with ballpoint pens To create typefaces that can be adapted to the pencil hardness scale, so that the ballpoint pen can now be used for a wide variety of purposes can.

Zur Lösung dieser Aufgabe werden erfindungsgemäß der Schreibpaste neben dem Grafit auch andere dunkle Farbpigmente, vorzugsweise Schwarzpigmente, zugesetzt Hierbei ist vorgesehen, den Grafitgehalt in der Schreibpaste gegenüber den genannten Farbpigmenten in nach der Härte zu bemessender Menge zu ändern, und zwar derart, daß für Schreibminen, die zur weichen Seite der üblichen Bleistift-Härteskala tendieren, der Grafitgehalt geringer zu halten ist als derjen.ige der dunklen Pigmente. Die letztgenannten bestehen beispielsweise aus auf Trägerstoffen (Kaolin) niedergeschlagenen Anilinfarbstoffen oder Ruß, die in der Pastenflüssigkeit nicht lösbar sind. Für Schriftbilder, die der härteren Seite der Bleistiftskala ange-paßt werden sollen, wird der Grafitgehalt größer gehalten als derjenige der dunklen Pigmente. Es können so durch jeweilige Wahl des Grafitgehalts alle Härtegrade erzielt werden.According to the invention, the writing paste is used to achieve this object in addition to graphite, other dark color pigments, preferably black pigments, Added here is provided as opposed to the graphite content in the writing paste to change the specified color pigments in the amount to be measured according to the hardness, and in such a way that for writing leads that are on the soft side of the usual pencil hardness scale tend to keep the graphite content lower than that of the dark pigments. The latter consist, for example, of deposited on carrier materials (kaolin) Aniline dyes or carbon black which are not soluble in the paste liquid. For Typefaces that are to be adapted to the harder side of the pencil scale, the graphite content is kept higher than that of the dark pigments. It can so all degrees of hardness can be achieved by choosing the graphite content.

So z. B. kann das Verhältnis gewählt werden: für die Härte B........ 50% Grafit 50% Schwarzpigment für die Härte F........ 70% Grafit 30% Schwarzpigment Für .die Härte 2H . .. .. . 90% Grafit 10% Schwarzpigment Der Charakter der Schriftbilder bzw. der Abstriche wird hierbei auch beeinflußt durch die Wahl der Gesamtmenge an Pigmenten im Verhältnis zum Dispergierungsmittel.So z. B. the ratio can be chosen: for hardness B ........ 50% graphite 50% black pigment for hardness F ........ 70% graphite 30% black pigment For hardness 2H. .. ... 90% graphite 10% black pigment The character of the typefaces or the smears is also influenced by the choice of the total amount of pigments in relation to the dispersant.
