The present invention relates to a composite tubular article for use as the fixing belt in an image-forming device such as a copying machine etc., particularly as a fixing belt suited for thermal fixing, and also relates to a process for producing the same.Conventionally known as an image-fixing belt is a belt consisting of a polyimide resin as the inner layer and a fluoroplastic as the outer layer. However, this fixing belt has problems that clear images cannot be obtained because the thickness of each layer is uneven, and that unglossed, so-called matt images cannot be obtained because the belt surface is smooth.This invention provides a composite tubular article comprising a tubular inner layer made of a polyimide resin and a tubular outer layer made of a fluoroplastic, the outer circumferential surface of the fluoroplastic tubular outer layer having a surface roughness of 1 to 10 .mu.m. The invention further provides, as a production process for the same, a process in which the outer layer is formed by use of a cylinder having an inner circumferential surface with a surface roughness of 1 to 10 .mu.m, and a polyimide-resin tubular inner layer is formed on the inner circumferential surface of the outer layer by converting a poly(amic acid) into a polyimide, or a process in which an inner layer formed by converting a poly(amic acid) into a polyimide is immersed in or sprayed with a fluoroplastic solution in which a particulate material of 5 .mu.m or smaller has been dispersed, thereby to form an outer layer.

摘要:
A method for producing optical disks each by bonding two disk substrates to each other through an adhesive sheet, which comprises the steps of: preparing a tape which includes a release tape, and a plurality of disk-like adhesive sheets arranged under a lower surface of the release tape at predetermined intervals; pressing the tape against an upper surface of a first disk substrate by an elastic material to thereby temporarily bond the first disk substrate to one of the adhesive sheets under the lower surface of the tape so as to form a temporarily bonded article; separating the release tape from the temporarily bonded article to expose the adhesive sheet; putting a second disk substrate on the exposed adhesive sheet and pressing the second disk substrate against the exposed adhesive sheet by the elastic material to thereby stick the second disk substrate to the temporarily bonded article so as to form a stuck article; and keeping the stuck article under a pressure or heat and pressure atmosphere to thereby bond the first and second disk substrates.
