The invention relates to protection from exposure to the environment, mainly ultraviolet radiation, and can be used in industry, Scania and adverse weather.

Due to the reduced thickness of the ozone layer in the atmosphere and appearance of a so-called ozone holes are tasked with the protection of man, animals and plants from ultraviolet radiation from the sun, as well as man-made ultraviolet radiation (hereinafter UV radiation), which is known to cause burns to the skin and stimulates the development of cancer, including melanoma. This increases the value of such materials, which modify the spectrum of light radiation.

A device for protection against solar radiation (WO, proposal 93/01733, A 54 B 25/18), made in the form of an awning and containing an armature, a support for a frame and a cover attached to the frame. The coating is made of burlap, in which openings are provided in various configurations, randomly distributed over the cloth covering and providing a modulated pass solar radiation.

This coating reduces the intensity of solar radiation and consequently proportionally reduces its UV component. However, the range of passing through the coating of the radiation remains unchanged.

It is known device, which may also serve to protect against ultraviolet the opening, and representing the greenhouse frame. The coating is made in the form of a polymeric film, which entered the compound of europium selected from the group comprising Eu(NO3)3Hairdryer, EuCl3TOPO, Eu(GFFA)3Hairdryer, Eu(TTA)3PD, Eu(TTA)3Hairdryer, Eu(VTFA)3Hairdryer, Eu(DBL)3DGSO, Eu(NO3)3TBP, EuCl33HCO, EuCl3DGSO where Hairdryer - 1,10 phenanthroline, TOPO - trioctylphosphine, GFA - hexafluoroacetylacetone, TTA - thenoyltrifluoroacetone, DP - 2,2-dipyridyl, BTFA - benzoyltrifluoroacetone, DBM - dibenzoylmethane, DGSO - Vexillology, TBP-tributyl phosphate, HCO - oil sulfoxidov formula RSO, where R is a hydrocarbon radical.

This coating not only absorbs UV part of the spectrum of the source light, and converts the UV part of the spectrum in red radiation, thereby increasing the share of the red component of the spectrum of the light source.

However, this coating keeps the light transforming the property for a period of not more than 60 days, as used for the manufacture of compounds of rare earth metals belong to the coordinate compounds. These compounds under the action of light decays rapidly. And thus already in 1 - 1.5 months of using the light shielding condition is achieved result is taken as a prototype device (EN, patent 2059999, C 08 L 23/02, published. 10.05.96) containing the greenhouse frame, which is fixed to the floor. The coating is made in the form of a polymeric film, which introduced a composite compound of General formula
