FIELD: chemistry.
SUBSTANCE: invention describes novel hydroxyphenyltriazine derivatives of general formula 
where R1 denotes H, C1-C12alkyl or OR3; R3 denotes H, C1-C18alkyl or C1-C12alkyl, possibly substituted with OH, C1-C18alkoxy group, COOR4 and/or -O-CO-R5; R4 denotes C1-C18alkyl; R5 denotes H; C1-C18alkyl; or C7-C11phenylalkyl; radicals E1' and E2', which are an aromatic carbocyclic condensed ring system, are described in the claim. The novel compounds are UV radiation absorbers and have absorption spectrum shifted towards the long-wave range with considerable absorption at up to 420 nm.
EFFECT: method of preparing a UV radiation stable composition which contains novel UV radiation absorbers, a method of stabilising organic materials and using novel compounds as UV light stabilisers for organic materials, particularly for motorcar coating.
