A tubular liner for the rehabilitation of an, in particular, underground sewer pipe, comprising at least: - an inner tubular film extending in the longitudinal direction of the tubular liner; - a resin-carrier layer extending in the longitudinal direction of the tubular liner and surrounding the inner tubular film, wherein the resin of the resin-carrier layer is curable with the aid of UV radiation; - a mechanically protective outer film system surrounding the resin-carrier layer and extending in the longitudinal direction of the tubular liner, - wherein the outer film system comprises at least one outer film (8; 8a, 8b) in the form of a UV-radiation- and short-wavelength, visible light-absorbing and/or -reflecting, single-layer or multi-layer film which contains, in one or more polymer layers, at least one short-wavelength, visible light-absorbing and/or - reflecting, organic or inorganic color pigment or a corresponding dye, and at least one organic or inorganic compound which absorbs and/or reflects the UV radiation, - wherein, the outer film system further comprises at least one mechanically stable reinforcing web (9; 9a, 9b) which rests on the aforementioned outer film (8; 8a, 8b), wherein the at least one outer film (8; 8a, 8b) is directed to the resin-carrier layer and the at least one reinforcing web (9; 9a, 9b), in the installed situation of the tubular liner, is directed to the sewer pipe wall, and wherein the outer film system has a transmittance for visible light at at least one wavelength in the range of 550 nm to 800 nm of at least 1%, wherein the at least one reinforcing web (9; 9a, 9b) comprises a fabric which preferentially predominantly or completely consists of polyester, wherein the fabric has a mesh size in the MD direction and/or in the CD direction of less than 2 cm, preferentially less than 1 cm, most preferentially less than 5 mm, with the MD direction being the machine direction, i.e. the processing direction during manufacturing and the CD direction being the transverse direction. - an inner tubular film extending in the longitudinal direction of the tubular liner; - a resin-carrier layer extending in the longitudinal direction of the tubular liner and surrounding the inner tubular film, wherein the resin of the resin-carrier layer is curable with the aid of UV radiation; - a mechanically protective outer film system surrounding the resin-carrier layer and extending in the longitudinal direction of the tubular liner, - wherein the outer film system comprises at least one outer film (8; 8a, 8b) in the form of a UV-radiation- and short-wavelength, visible light-absorbing and/or -reflecting, single-layer or multi-layer film which contains, in one or more polymer layers, at least one short-wavelength, visible light-absorbing and/or - reflecting, organic or inorganic color pigment or a corresponding dye, and at least one organic or inorganic compound which absorbs and/or reflects the UV radiation, - wherein, the outer film system further comprises at least one mechanically stable reinforcing web (9; 9a, 9b) which rests on the aforementioned outer film (8; 8a, 8b), wherein the at least one outer film (8; 8a, 8b) is directed to the resin-carrier layer and the at least one reinforcing web (9; 9a, 9b), in the installed situation of the tubular liner, is directed to the sewer pipe wall, and
