A seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired.

According to at least one embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (γ) a hard coat on at least one surface of (α) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4′-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %. According to another embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (γ) a hard coat on at least one surface of a transparent laminate film constituted of (α) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4′-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol, when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %, and (β) a poly(meth)acrylimide resin film.

A process for producing a resinous panel which is for use as at least some of the front panel of an article, the process including (A) a step in which a resin sheet having a thickness of 0.5-10 mm is fixed to a working table and (B) a step in which the resin sheet is punched out by forcing a Thomson blade into the resin sheet approximately perpendicularly thereto from the side where the surface of the resin sheet is to be the outer surface of the article, thereby obtaining the front panel, wherein (C) the Thomson blade is a double-edged blade having an edge angle of 30-60 degrees. The resin sheet has a tensile modulus of preferably 1,500 MPa or greater. Preferably, the resin sheet includes a transparent resin sheet layer and a colored resin sheet layer in this order from the surface that is to be the outer surface of the article. The colored resin sheet is one which does not break when a DuPont impact test was conducted in accordance with ASTM-D2794 in a 0° C. environment under the conditions of a height of 50 cm, an impactor diameter of 1 inch, an impactor weight of 1 Kg, and a pedestal diameter of ½ inch.
