摘要： PURPOSE:To obtain a magnetic tape which has an excellent S/N ratio and superior running durability, causes less dropouts, and is free of tape-edge folding, by providing a magnetic layer on the top surface of a nonmagnetic base and an undercoat layer on the reverse surface, and by forming a back layer on the undercoat layer to thickness less than a specific value. CONSTITUTION:On the surface of a base, such as a polyehtylene terephtalate film, a magnetic layer is formed and on the reverse surface, a solution of saturated polyester resin obtained by depolymerizing polyethylene terephtalate and polymerizing it by adding a new diol component or by polymerizing various diol components and various dibasic acids is applied and dried, thereby forming an undercoat layer with about 0.1-0.2mum thickness after said drying treatment. On the undercoat layer, a

摘要： PURPOSE: The direct esterification between terephthalic acid and ethylene glycol forms oligomers, which is decomposed with an excess amount of EG, then the polycondensation reaction is effected, thus producing polyester with high transparency and polymerization degree.
CONSTITUTION: To bishydroxyethyl terephthalate (BHET) oligomers resulting from the direct esterification of terephthalic acid (TPA) with EG are continuously added a slurry of EG/TPA at a molar ratio of less than 1.2/1.0 and they are heated. The newly formed BHET is separated and transferred to the polycondensation tank and EG is added so that EG/TPA molar ratio becomes 1.2W2.0. Thus, polyester with a diethylene glycol content of less than 2% and high polymerization degree is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a process for producing a base which has good transparency and excellent curling resistance and is adequately usable not only for sheet applications but for roll applications as well. SOLUTION: The polyester used for this base is obtd. by bringing a dicarboxylic acid component consisting essentially of naphthalene-2,6-dialkyl ester dicarboxylate and a dial component consisting essentially of ethylene glycol into polycondensation reaction. A specific ratio of manganese, magnesium, antimony and phosphorus are incorporated therein. An anthraquinone dye is incorporated into the resulted polyester which is 7.0 to 0.5 in the melting electric resistance value (logR) expressed by the common logarithm in a molten state at 300 deg.C and 0.49 to 0.65 in the ultimate viscosity measured at 25 deg.C in a soln. of a mixture composed phenol/tetrachloroethane (6/4 by weight). Such polyester is subjected to film forming by an electrostatic impressing method and biaxial stretching, by which the polyester film having the excellent hue, transparency, etc., is obtd.

摘要： PURPOSE:To provide a producing method of photographic substrate, by which the oligomers are hardly generated at the time of forming the substrate film and the film having a low foreign matter content can be produced and further, the reduction in transparency of the film can be prevented from occurring by melt-extruding a polymer obtained through subjecting a polyester prepolymer to heat treatment at a specified temp., into a sheetlike form and then uniaxially stretching the sheet. CONSTITUTION:This substrate is produced by subjecting a polyester prepolymer to heat treatment in a gaseous nitrogen stream or under vacuum, at a temp. which satisfys the formula I, so that the intrinsic viscosities of both prepolymer and resulting polymer after the heat treatment satisfy the formula II, thereafter melting and extruding the resulting polymer into a sheetlike form and then uniaxially stretching the sheet. In the formulas I and II: Tb is the boiling point ( deg.C) under atmospheric pressure of the major glycol component of the polyester prepolymer; T is the heat treatment temp. ( deg.C); Tm is the melting point ( deg.C) of the polyester prepolymer; IV0 is the intrinsic viscosity of the polyester prepolymer; and IV is the intrinsic viscosity of the resulting polymer after the heat treatment of the polyester prepolymer.
