Definitions
- the invention relates to a method for reversibly changing the color of materials.
- Patent application 19833176.2-52 describes the use of sodalite, which is based on the reversible discoloration of the mineral in daylight. This discoloration depends on the UV component in visible light. From US Pat. No. 5908499 and Abstract 1999 346957 it is known to produce a color powder from minerals, such as sodalite, chemical or thermal pretreatment and radioactive radiation being required alone or in combination to achieve the colors.
- Patent DE 3530902 describes the use of gemstone powder, which also includes sodalite, with carrier materials for cosmetic purposes as a dye for decorative purposes.
- the utility model G82 16479.7 describes the use of sodalite as a wall plate.
- the cited inventions use existing color pigments, which may be irreversibly changed by treatment.
- the claimed minerals are not reactive in the sense of a change in color due to daylight.
- the invention has for its object to show a method to reduce the influence of harmful UV rays by a reversible change in color of materials.
- the red coloring of sodalite in the presence of UV light results in additional applications of the mineral as a color pigment.
- the mineral can be used in finely powdered form as the only coloring component to other materials be added. However, it can also be added as a color component to a colored material. Depending on the concentration of soda-lite pigments, there is a more or less severe discoloration, which can be caused over the entire surface, selectively or structurally.
- the glass turns red as soon as daylight hits the glass surface. This creates an optical effect in the form that, for example, a facade turns red, which only occurs during the day.
- the discoloration of the glass prevents the penetration of longer-wave light, such as long-wave UV radiation and heat radiation.
- the discoloration also has a protective function when used in spectacle lenses and windshields. These change color when exposed to UV light and reduce the passage of visible light.
- plastic windows and roofs such as polyacrylic materials
- the discoloration of parasols or awnings works in a similar way: in sunlight, the material discolors and at the same time offers decorative sun protection. Only as much sunlight is let through as corresponds to the tolerable UV radiation.
- This special application can be provided by setting a sufficient concentration of pigments according to the invention.
- sodalite pigments When sodalite pigments are added to colored materials, a color change occurs in daylight. For example, during the day green glasses, the facades of houses or other materials treated according to the invention turn blue due to the complementary color red. By adding sodalite to binders, the entire surface or parts can be discolored in daylight.
- This color change can be used for special advertising purposes.
- Company logos appear in a different color than, for example, the surrounding color of a facade.
- the color pigments according to the invention can be admixed already during the production of colors and glazes. This gives the user the option, for example, of changing the color of components.
- Adding the color pigments to car paints would have the effect that, for example, a car would change completely or partially in daylight from green to blue or from white to red.
- the change from colorless to red or from a complementary color such as green to blue can also be used for jewelry and fabrics.
- the wearer of such an article provided with sodalite pigments has, for example, a differently colored garment during the day than in artificial light.
- the discoloration can follow fashionable patterns, for example, through targeted pigmentation of material components. This discoloration is also clearly visible, for example, in discotheques with UV light effects.
- Another fashionable use of the invention is the color pigmentation of nail polish and hairspray. As a result, the wearer has a hair color that differs between day and night.
- Another application according to the invention is to use the color change, e.g. B. from green to blue, as a filter for light.
- the color change e.g. B. from green to blue
- This effect can be used for optical switching processes, for example.
- the color pigment according to the invention can also be used for securing and marking documents, such as bank notes.
- the reversible discoloration is used to recognize the authenticity of a document.
- the admixture of the color pigments according to the invention can be used in paper and plastic products for decoration and advertising.
- Another possible application which is based on the discoloration of materials treated according to the invention, is the use of the discoloration as a trigger for switching operations or signaling.
- glass or surface discoloration can be used as a light measurement, which in turn is used as a signal generator for switching processes.
- the discoloration of the sodalite represents a robust, uncritical type of measurement of UV light, which is therefore superior to interference-sensitive light measurement and display methods. Further advantageous applications result from the subclaims.
