| titleOfInvention | Photosensitive identification mark |
| abstract | The utility model relates to means of object identification and can be used to improve the reliability of protection against counterfeiting and control the authenticity of various valuable documents and products using a photosensitive identification mark applied with photochromic ink based on bacteriorhodopsin by piezoelectric inkjet printing. The photosensitive label contains a layer of photochromic composition located on the substrate, which is formed by the method of piezoelectric inkjet printing with photochromic ink based on a suspension of bacteriorhodopsin in the form of fragments of purple membranes 25--250 nm in size, obtained after ultrasonic treatment of a suspension of purple membranes in an aqueous solution of a polymer binder, and gelatin at the following ratio of components: 1 ÷ 20 mass. including bacteriorhodopsin; 1 ÷ 10 mass. including, a polymeric binder, preferably polyvinyl alcohol, or polyvinylpyrrolidone, or polyethylene oxide, or polyacrylamide, or hydroxyethylcellulose; 30 ÷ 85 mass. h. water; 0.05 ÷ 2.5 wt. including gelatin. The technical result consists in ensuring long-term preservation of the photochromic properties of the active component - bacteriorhodopsin, with homogeneous and uniform distribution of bacteriorhodopsin in the layer of labels of various shapes with a high-quality image and high resolution of a graphic or pictorial drawing. 7 p.p. f-ly, 1 dwg |
