Description

Photochemisches Lackierverfahren. Zusatz zum Patent 447 5o6. Durch das Patent 447 5o6 ist ein photochemisches Lackierverfahren bekannt geworden, bei dem die zu verzierenden Gegenstände mit :einem öllöslichen Lack, bestehend aus fossilen Harzen, Kunstharzen, und Anilinfarben, überzogen, dann unter einem Negativ belichtet und darauf die unbelichteten Stellen mittels eines Mineralöls ausgewaschen werden: Bei diesem Verfahren kann es nun vorkommen, daß die aufzubringende Zeichnung, namentlich wenn es sich um feinlinige Muster handelt, nicht in voller Klarheit erhalten wird, wenn die Lackunterlage aus faserigem oder porösem Material, z. B. Holz, besteht. In diesem Fall dringt nämlich der farbstoffhaltige Lack in die Poren der Unterlage ein und läßt beim Entwickeln den Farbstoff in den Poren zurück. Es wird also auch an den unbelichteten Stellen, die rein weiß bzw. von der Farbe der Unterlage sein sollten, eine Färbung entstehen, deren Stärke ganz davon abhängig ist, wieviel Farbstoff sich in den Poren festgesetzt hat. Die Linien des Musters m erden dann verschwimmen und unklar erscheinen.Photochemical painting process. Addendum to patent 447 5o6. By the patent 447 5o6 a photochemical painting process has become known, at the objects to be decorated with: an oil-soluble varnish, consisting of fossil Resins, synthetic resins, and aniline paints, coated, then exposed under a negative and then the unexposed areas are washed out with a mineral oil: With this method it can happen that the drawing to be applied, namely if it is a fine-line pattern, is not obtained in full clarity, if the lacquer base made of fibrous or porous material, e.g. B. wood. In this case, the dye-containing lacquer penetrates into the pores of the substrate and leaves the dye in the pores during development. So it will too in the unexposed areas that are pure white or of the same color as the base should result in a coloring, the strength of which depends entirely on how much dye has settled in the pores. The lines of the pattern will then become blurred and appear unclear.

Dieser Nachteil soll gemäß der vorliegenden Erfindung dadurch vermieden werden, daß man vor Beginn des in der Patentschrift 447 5o6 beschriebenen Verfahrens eine farblose Lackschicht auf den -zu lackierenden Gegenstand aufträgt. Diese Lackschicht füllt die Poren des Holzes aus und verhindert nach dem Trocknen das Eindringen von Farbstoff in die Poren. Zweckmäßig wird als Grundschicht ein gleichfalls mittels Mineralölen löslicher Lack aus fossilen Harzen und Kunstharzen ohne Farbzusatz verwendet, so daß sich diese Lackschicht an den unbelichteten Stellen mitsamt der Farblacküberschicht auswaschen läßt, während sie an den belichteten Stellen durch den unlöslich gewordenen Farblack geschützt ist.This disadvantage is intended to be avoided according to the present invention be that one before the beginning of the process described in patent specification 447 5o6 Applying a colorless layer of lacquer to the object to be lacquered. This layer of varnish fills the pores of the wood and prevents penetration after drying Dye in the pores. A likewise medium is expediently used as the base layer Mineral oils-soluble varnish made from fossil resins and synthetic resins with no added color used, so that this lacquer layer is in the unexposed areas together with the colored lacquer layer can be washed out while they have become insoluble in the exposed areas Color lacquer is protected.

Das Verfahren der vorliegenden Erfindung geht also nunmehr so vor sich, daß man den zu verzierenden porösen Holzgegenstand zunächst mit einem farblosen Lacküberzug versieht. Dann wird eine zweite Schicht aus mineralöllöslichemLack mit einem Zusatz von Aniaffarben aufgebracht und diese Schicht unter einem Negativ belichtet. Wird der Gegenstand nun mit Mineralölen behandelt, so werden an den unbelichteten Stellen sowohl der farblose als auch der gefärbte Lack ausgewaschen, so daß der Untergrund frei sichtbar wird. An den belichteten Stellen dagegen ist der Farblack infolge des als. Sensibilisator wirkenden Farbkörpers unlöslich geworden, so daß das Muster in der Farbe der zweiten Lackschicht klar sichtbar ist. Die Zusammensetzung des Lackes ist die gleiche wie bei dem Verfahren nach Patent 447 5o6.The method of the present invention now proceeds as follows The fact that the porous wooden object to be decorated is first coated with a colorless one Lacquer coating provides. Then a second coat of mineral oil-soluble paint is applied an addition of Aniaf colors applied and this layer exposed under a negative. If the object is now treated with mineral oils, the unexposed Make both the colorless and the colored paint washed out so that the Subsurface becomes freely visible. On the other hand, the colored lacquer is in the exposed areas as a result of the as. Sensitizer-acting dye has become insoluble, so that the pattern is clearly visible in the color of the second layer of lacquer. The composition of the varnish is the same as in the method according to patent 447 506.
