FIELD: chemistry.
SUBSTANCE: polymeric composition is a concentrate in the form of granules or the concentrate diluted with the thermoplastic polymer. The concentrate comprises a thermoplastic polymer, a luminescent additive - inorganic crystal phosphor based on yttrium oxysulphide, or yttrium oxide, or yttrium phosphate-borate, activated with europium or europium and bismuth transforming UV radiation into the red spectral band, a light stabiliser based on sterically hindered amine - Tinuvin 622 - and hydrophilizing additive - antifog - sorbitol monostearate. The thermoplastic polymer can be used as polyethylene and copolymers of ethylene.
EFFECT: increase in service life of luminescent additive and film material for agricultural purpose.
