The present invention relates to a multilayer thermoformable composite synthetic veneer film, furniture parts produced therefrom, and a process for producing the same. The base layer comprising polyolefin has a thickness of 100 to 500 .mu.m and a particular composition and is composed of at least three different polyolefins. The film also includes at least one intermediate layer in the form of at least one primer layer, bonding layer or bonding film or, respectively, bonding layer; an optional printing layer, coloring layer or color-printing layer arranged over part or all of the surface; at least one polyester-containing single- or multiple-layer-structure layer or film; at least one bonding layer, adhesion-promoting layer or reactant layer on the side of the base layer that is to be applied to a substrate; and a surface-covering layer on the top of the film.

[ What is claimed is:] [1.]1. A multilayer thermoformable composite synthetic film, comprising:(1) at least one base layer comprising polyolefin and having a thickness of 100 to 500 .mu.m, which comprises, based on 100 parts by weight of polyolefin, from 0 to 90 parts by weight of (i) at least one inorganic and/or organic filler, pigment or filler-pigment mixture, (ii) at least one UV stabilizer and/or (iii) heat stabilizer and/or (iv) antioxidant, wherein the base layer comprises (a) at least one propylene copolymer containing ethylene and having a Vicat softening point VST/A/50 of from 110 to 130.degree. C. and a melt index MFR (230/2.16) of from 1 to 10 g/10 min, (b) at least one polyethylene, and (c) at least one polyethylene elastomer or polyethylene-containing elastomer;(2) at least one first intermediate bonding layer;(3) at least one polyester-containing layer comprising an amorphous polyester having a Vicat softening point VST/A/50 of from 60 to 90.degree. C.;(4) at least one bonding layer, adhesion-promoting layer or reactant layer arranged on the underside of the base layer; and(5) a surface-covering layer arranged on top of the film.
