Description

Nachleuchtende, nicht vergrauende und wetterbeständige Filme bildende Anstrichmittel Die zur Zeit im Handel befindlichen nachleuchtenden Pigmente sind unbeständig gegen Bestrahlung mit ultraviolettem Licht und Feuchtigkeit. Alle natürlichen und synthetischen Bindemittel sind weitgehend für die ultraviolette Strahlung durchlässig, so daß diese zur Einwirkung auf die Pigmente kommt. Viele durchgetrocknete Anstrichfilme werden sodann im Laufe der Alterung aufnahmefähig für Wasser und quellbar, bei der Außenbewitterung nehmen sie infolgedessen Feuchtigkeit an. Eine Folge dieser Vorgänge ist, daß bei Leucht-Lackfarben unter Außenbewitterung schon nach wenigen Tagen ein Grauwerden und demzufolge ein Absinken in dem Nachleuchten auftritt.Photoluminescent, non-graying and weather-resistant films Paints The afterglow pigments currently on the market are not resistant to exposure to ultraviolet light and moisture. All natural and synthetic binders are largely transparent to ultraviolet radiation, so that it acts on the pigments. Lots of dry paint films then become receptive to water and swellable in the course of aging As a result, they absorb moisture from outdoor exposure. A consequence of these processes is that with luminous paints exposed to outdoor weathering after a few days Turning gray and consequently a drop in afterglow occurs.

Es sind zwar Substanzen bekannt, welche die Erscheinung des Grauwerdens überlagern und eine aufhellende Wirkung ausüben, ferner Papier gegen ultraviolettes Licht schützen, dabei vollzieht sich aber ein Vorgang der Aufhellung im Bereiche des für uns wahrnehmbaren Lichtes.It is true that substances are known that cause the appearance of graying overlay and exert a lightening effect, furthermore paper against ultraviolet Protect light, but a process of lightening takes place in the area of the light that is perceptible to us.

Bei dieser Erfindung handelt es sich jedoch um die Abschirmung der für uns nicht wahrnehmbaren kurzwelligen Strahlung auf Zinksulfid, so daß dies nicht zersetzt wird. Diese Schutzmaßnahme betrifft einen engbegrenzten Wellenlängenbereich. Die Wirkungsdauer des Zinksulfides als Träger des Nachleuchtens wird dadurch verlängert.In this invention, however, it is the shielding of the for us imperceptible short-wave radiation on zinc sulfide, so this is not is decomposed. This protective measure concerns a narrowly limited wavelength range. The duration of the effect of the zinc sulfide as a carrier of the afterglow is prolonged.

Es wurde gefunden, daß man zu nachleuchtenden, nicht vergrauenden und wetterbeständige Filme bildenden Anstrichmitteln kommt, wenn dem keine Wasseraufnahme zeigenden Bindemittel Substanzen zugefügt werden, welche ultraviolette Strahlen besonders in dem Bereiche von 0,24 bis 0,42 My reflektieren und das Pigment gegen diese abschirmen. Das Bindemittel kann hierbei von sich aus wasserabweisend oder durch eine besondere Imprägnierung in bekannter Weise wasserabweisend gemacht sein.It has been found that one becomes afterglowing, not graying out and weather-resistant film-forming paints come when there is no water absorption substances that show ultraviolet rays are added to the binder reflect especially in the range from 0.24 to 0.42 My and the pigment against shield these. The binder can be water-repellent or water-repellent by itself be made water-repellent in a known way by a special impregnation.

Durch Zugabe von Salicylsäurephenylester als Ultraviolett-Strahlung reflektierender Substanz zu wasserunempfindlichen Bindemitteln werden Anstrichfilme erhalten, die die ultraviolette Strahlung stark abschirmen und so ihre Leuchtkraft behalten.By adding phenyl salicylate as ultraviolet radiation reflecting substance to binders insensitive to water become paint films obtained, which shield the ultraviolet radiation strongly and thus their luminosity keep.

Die Zusammensetzung eines solchen Anstrichmittels wird nachstehend angegeben: Polyacrylsäureester 12 Teile, Weichmacher 2 Teile, Glykolacetat 21 Teile, Butanol 24 Teile, Salicylsäurephenylester 1,8 Teile und Leuchtpigment 40 Teile.The composition of such a paint is as follows indicated: polyacrylic acid ester 12 parts, plasticizer 2 parts, glycol acetate 21 parts, Butanol 24 parts, salicylic acid phenyl ester 1.8 parts and luminous pigment 40 parts.
