SUBSTANCE: invention relates to a composite decorative sheet, for example, for wall coverings and wallpaper, and a method for producing a foamed decorative sheet. Composite sheet comprises or consists of the following components: (i) a base layer with a modulus of elasticity of more than 1 GPa and (ii) a foamable layer attached to the base layer. Foamable layer comprises or consists of the following components: 100 parts by weight of a polyolefin material in which the modulus of elasticity is less than 0.1 GPa, from 0.1 to 10 parts by weight of a foaming agent; and from 0 to 200 parts by weight of additives. Foamable layer has a thickness between 0.05 and 0.3 mm.
EFFECT: invention provides an environmental decorative material that is environmentally friendly and does not exhibit a twisting effect.
