FIELD: process engineering.
SUBSTANCE: invention relates to protection of cork or wood substrates against colour change. Proposed method comprises application of coat onto substrate that contains minor amounts of inorganic UV-ray absorbers and surplus organic absorbers in coat material. Organic UV-absorber comprises hydroxibenzophenone, hydroxiphenylazimido-benzene, oxanalide, andjydroxiphenyltriazine abosorbers of UV rays corresponding to formulae (I),(II),(III) and (IV), and mixes thereof. Inorganic absorber comprises translucent iron oxide, titanium oxide, zinc oxide and cerium oxide, as well as carbon black, ad mixes thereof.
EFFECT: stabilisation of colour of definite paints, reduced fading of initial paint.
