Dl «the present invention relates to a sign, in particular for advertising purposes using rüekstrahleftder materials»

The invention is based on the recognition _8, wherein the attachment of glass balls on a reflective * nd * ri Under · * reason, the reflection of Roe "kstranl * ndem material in specular background" ore is judged as the re-radiation of material having a diffusely reflective substrate possesses · The invention aims to create a sign, the appearance of which changes with the viewing angle »

The essential feature of a sign according to the invention is that display elements are arranged on a surface, with one part of the display elements having a specularly reflective surface and another Part of the display elements is assigned a diffusely reflective surface and the parts of the display elements at least partially with small translucent Balls are covered

A preferred embodiment of signs according to the invention has a background with a specular reflective surface and display elements on this, W with parts of the display elements consisting of one or more translucent layers and other parts of one or more opaque layers and with the parts of the display elements at least partially are covered with small translucent balls.

With such characters, according to observers of different in different directions reflective properties of the parts of the display elements will determine on moving past the sign that it changes see his off, and it is immaterial whether the sign ■■ 'is illuminated by light sources with him the Beobachfc ter nitbewegen (automobile headlamp) or illuminated by stationary light sources · from one to the mark in substantially vertical viewing angle • inen parts of the presentation elements are "ore prominent than the other part ·, while from an acute to mark loading • trachtungswinkel the other parts appear brighter than that

serves as an adhesive! to attach the balls to the sign. The spheres are preferably glass spheres with a diameter of about 0.15 to 0.30 mm.

A particularly effective sign is formed by removing individual pieces of the display elements, e.g. Letters, consist of an area of translucent paint and an area of opaque paint, where E.g. the middle area consists of one color type and the contour consists of the other color type. With such a sign the affected pieces will emerge over a wide range of viewing angle, from some points however, they are mainly seen as full, light letters, whereas other points have a light outline darker inner part is seen.

The background preferably consists of a metallized plastic film, which can be colored or colorless. A preferred substrate consists of a metallized vinyl polyester or cellulose acetate film on its back is provided with a pressure-sensitive adhesive. If desired, such a substrate can extend over the entire surface of the Character extend, with the areas outside of the print with transparent, opaque or matt colors can be overprinted as desired.

The surface coating compounds are ordinary colors that are applied to the substrate using printing processes, E.g. gravure printing can be applied. The translucent masses should be transparent or at least as far as possible be translucent so that the effect of the reflective background can be seen from the front of the sign. So-called Flamboyant paints are well suited for this purpose. The opaque masses can be pigment colors that have similar physical properties to the translucent ones Have colors. They can be white or any-

another light color that is a suitable one has diffuse reflection

The invention will now be explained in more detail with reference to the drawing, which shows an exemplary embodiment explained.

It shows:

Fig. 1 is a plan view of a character according to FIG. Invention and

Fig. 2 is a schematic section along the Line H-II to FIG. 1 on an enlarged scale.

In the case of the characters in FIGS. 1 and 2, the background consists of a polyester film 10 which is 0.025-0.05 mm thick 1st, which is further metallized with an aluminum coating 11 and is coated on its rear with a pressure-sensitive adhesive 12

During the production of the sign, display elements 13 are screen-printed onto the reflective surface of the base. As shown in FIG. 1, the display elements are made up of two parts formed, for example each letter from an inner area 14 of transparent color and a contour area 15 of a light-colored opaque paint. The areas of the sheet outside of the imprint can be marked with a opaque or matt color 16 can be printed. Suitable colors for this purpose are plasticized screen printing inks based on nitrocellulose · those in the case of translucent colors using soluble or highly dispersed dyes Pigments are colored in conventional ways · Where matte colors are needed, such as for the areas outside of the Imprint, where conventional colors with coarser pigment are suitable.Preferably each color is left dry, before the next one is printed.

209808/0727

When all the colors have been printed and dried, a layer 17 is applied to a colorless and Essentially transparent varnish applied over the imprint by screen printing · A suitable for such a varnish Mixture consists of an alkyd varnish made from pentaerythritol and phalic acid anhydride and modified with linseed oil was decorated, together with aluminum oxide as a filler and white fuel as a diluent

Before the lacquer layer 17 dries, balls 18 with an average diameter of 0.15-0.30 mm are applied and they are bound to the sheet in the area of the print by the dry varnish. If desired, a thin one can be used Protective layer of clear polyurethane or other varnish over applied to the balls.

It goes without saying that the expression "sign ¹¹ " used here is not restricted to any particular embodiment or field of application, but on the contrary includes any object which forms or is provided with elements of representation and which is intended to be conspicuously visible.
