Verfahren zur Herstellung gefärbter geformter Gegenstände aus durch Erwärmen und unter Druck zu härtenden Stoffen.
Die Herstellung von geformten Gegenständen, wie Knöpfen u. dgl., aus durch Erwärmen und unter Druck zu härtenden Stoffen, wie natürlichen und künstlichen Harzen und Kaseinmassen, kann derartig erfolgen, dass man das Material in der Heisspresse presst oder bereits fertige Tafeln bearbeitet oder das verflüssigte Material in Formen giesst.
Hiebei besteht der Übelstand, dass eine Musterung mit verschiedenen Zeichnungen und Farben entweder überhaupt nicht oder nur unvollliommen möglich ist. Die Aufbringung einer Zeichnung kann nur derartig erfolgen, dass das fertige Material mit Farbstofflösungen oder Farbstoffmischungen besprengt wird. Hiebei hat sich gezeigt, dass eine haltbare Färbung nicht möglich ist.
Die angestellten Untersuchungen über den Grund dieser Erscheinung haben ergeben, dass die Ursache in der mangelnden Porosität zu erblicken ist. Die Färbung erfolgt erst. wenn bereits zusammenhängende Massen vorliegen. Diese zusammenhängenden Massen nehmen aber nicht in genügender Weise Farbstofflösungen oder Farbstoff- mischungen auf.
Es hat sich nun gezeigt, dass eine vorteilhafte Färbung unter Verwendung von Schablonen zu erzielen ist, wenn man zunächst das am besten in Pulverform zerkleinerte

Die so erhaltenen, noch porösen, aber bereits geformten Gegenstände werden unter Schablonen gebracht und dann in der bekannten Weise mit Farbstoffmischungen oder Farbstofflösungen. zum Heispiei durch Spritzen oder Zerstäuben, behandelt. Hierauf erfolgt die Fertigstellung der Gegen- stande in bekannter Weise durch Erhitzen, gegebenenfalls unter Anwendung von Druck.

Process for making colored shaped articles from materials to be hardened by heating and under pressure.
The manufacture of shaped articles such as buttons and the like. Like., from substances to be hardened by heating and under pressure, such as natural and artificial resins and casein masses, can be done in such a way that the material is pressed in a hot press or finished sheets are processed or the liquefied material is poured into molds.
The disadvantage here is that a pattern with different drawings and colors is either not possible at all or only partially. A drawing can only be applied in such a way that the finished material is sprinkled with dye solutions or dye mixtures. It has been shown here that durable coloring is not possible.
The investigations made into the reason for this phenomenon have shown that the cause can be seen in the lack of porosity. The coloring only takes place when coherent materials are already present. However, these coherent masses do not sufficiently absorb dye solutions or dye mixtures.
It has now been shown that an advantageous coloring can be achieved using stencils if one first comminutes the, best in powder form

gives a lying shape, but still retains the porosity. For example, the user is treated in a tablet machine or other molding machine. The thus obtained, still porous, but already shaped objects are placed under templates and then in the known manner with dye mixtures or dye solutions. for heat treatment by spraying or atomizing. The objects are then finished in a known manner by heating, if necessary with the application of pressure.
The present process is particularly suitable for condensation products from formaldehyde and phenols; the intermediate product is used which is formed during this rondensation.
The dyes that can be used are both inorganic and organic in nature. you
