Zusammenfassung:	A light-sensitive protective marking for visual identification comprises a base, to the internal surface of whiсh is fixed, by means of an adhesive preparation, a layer of a photochromic composition in the form of a gelatin film containing incorporated and suspended bacteriorhodopsin and a bacteriorhodopsin-property modifier with a thickness of 10-30 µm, and a protective layer consisting of an optically transparent film which is easily destructible upon removal and is attached to the base and to the layer of the photochromic composition by means of an optically transparent glue, in the following ratio of components of the photochromic composition: 3.0-7.0 parts by weightof bacteriorhodopsin; 55-75 parts by weightof gelatin; and 20-40 parts by weight of bacteriorhodopsin-property modifier. L'étiquette de protection photosensible pour identification visuelle comprend un substrat sur la surface interne duquel on a fixé au moyen d'une couche d'adhésion une couche de composition photochrome se présentant comme un film de gélatine à laquelle sont intégrés une bactériorhodopsine en suspension et un modificateur des propriétés de la bactériorhodopsine ayant une épaisseur de 10÷30 micromètres et une couche de protection en un film optiquement transparent facilement destructible à l'enlèvement qui est fixé au substrat et à la couche de composition photochrome au moyen d'une couche de colle optiquement transparente, avec le rapport suivant des composants de composition photochrome : bactériorhodopsine 3,0÷7,0 fractions massiques ; gélatine 55÷75 fractions massiques; modificateur des propriétés de la bactériorhodopsine 20÷40 fractions massiques. Светочувствительная защитная метка для визуальной идентификации содержит подложку, на внутренней поверхности которой посредством адгезионного состава закреплен слой фотохромной композиции в виде пленки из желатина со встроенным - взвешенным бактериородопсином и модификатором свойств бактериородопсина толщиной 10÷30 мкм, и защитный слой из легко разрушаемой при удалении оптически прозрачной пленки, прикрепленной к подложке и к слою фотохромной композиции посредствам оптически прозрачного клея, при следующем соотношении компонентов фотохромной композиции: бактериородопсин 3,0÷7,0 масс. ч.; желатин 55÷75 масс. ч.; модификатор свойств бактериородопсина 20÷40 масс. ч.
