FIELD: technological processes.

SUBSTANCE: method includes application of acrylic foam paint on fibrous base, subsequent preliminary drying of applied layer at the temperature of 80-120°C and foaming of acrylic foam paint layer by means of drying at the temperature of 120- 160°C. Prior to application of acrylic foam paint on fibrous base printed pattern is applied, and prior to foaming 25-30% aqueous solution is applied onto layer of acrylic foam paint, at that solution contains binding agent on the basis of polyvinyl acetate copolymer and decorative material at their ratio accordingly from 1:1 to 1:0.2 in amount of 8-10% from foam paint mass. At that application of foam paint is carried out with mass of dry coating of 10-25 g/m². In suggested method decorative material is material selected from group that contains polyethylene terephthalate and aluminium foil with particle size of 0.1-0.5 mm. As binding agent on the basis of polyvinyl acetate copolymer composition is used that contains dispersion of polyvinyl acetate copolymer dispersion, defoaming agent, biocide and water.

EFFECT: expansion of foamed wallpapers assortment.
