FIELD: suspension polyvinyl chloride compositions can by used for manufacturing films of agricultural purpose. SUBSTANCE: invention makes it possible to increase service life of luminescent films due to the fact that the composition comprises as the light transforming additive a compound of formula: Eu(TTA) (ТТА)3 phene wherein TTA is tenoyltrifluoroacetone, phene is 1,10-pheneanrhrolone, or Eu (HFAA)(HFАА)2*2TPhPho is where HFAA is hexafluoroacetyl acetone, TPhPho is triphenylphosphine oxide or mixtures thereof the composition comprises 0.1-0.5 wt. % coprecipitated barium ad cadmium stearate as stabilizer or 0.2-1.4 wt. lead acetate and further comprises 0.05-1 wt. % TPhPho, the composition also comprises 22-35 wt.% plasticizer. EFFECT: improved properties of the polymeric composition. 1 tbl
