MATERIAL FOR MAKING LIGHT-CORRECTING POLYMER FILM Russian patent published in 2016 - IPC C09K11/08 C08L23/02 B82Y20/00 B82Y30/00 

FIELD: packaging industry.

SUBSTANCE: invention relates to a material for making a light-correcting polymer film, which can be widely used as light-converting material. Material comprises a thermoplastic polymer based on polyolefins, hydrocarbons of paraffin series in an amount of not more than 4.5 wt%, a light-stabilising additive not more than 5.0 wt% and 0.01-1.0 wt% fluorescent additive - quantum dots with a given effective band-gap, distributed in volume of polymer. Material can additionally contain not more than 5.0 wt% plasticiser, not more than 0.1 wt% surfactant, not more than 1.0 wt% antioxidant, not more than 3.5 wt% light-diffusing additive.

EFFECT: invention provides improved photostability of light-correcting film and efficiency of converting natural light with reduction of toxicity of material.
