Abstract: A thermoplastic resin film has a variation in thickness of the film in the longitudinal direction of not more than 5% and a ratio "Pw1/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 0.15 to 0.45 (1/m) (Pw1) to the sum of spectral intensities of the full wave-number range (PwT) determined when a wave form of the variation in thickness is subjected to analysis of Fourier transformation of not more than 0.20, and/or a variation in thickness of the film in the longitudinal direction of not more than 5% and a ratio "Pw2/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 1.00 to 2.00 (1/m) (Pw2) to the sum of spectral intensities of the full wave-number range (PwT) determined as described above of not more than 0.15. A process for preparing a film which may have either of the above characteristics comprises supplying a thermoplastic resin to a die after heating and melting it at a temperature of not lower than a melting-finishing temperature "Tme"; extending the resin in a manifold of the die in the width direction of the die; cooling the resin in a land of the die at a temperature of lower than the melting-finishing temperature "Tme" and not lower than a crystallization starting temperature caused in cooling "Tcb"; and extruding the resin from the die.

Abstract: A biaxially oriented polyester film wherein the ratio (=IMD /IND) of the peak intensity (IMD) in the longitudinal direction to the peak intensity (IND) in the thickness direction determined at 1615 cm by laser Raman scattering method is not less than 6; and a process for production of a biaxially oriented polyester film which comprises the steps of controlling the ratio (A/B) of the maximum thickness (A) of the edge portion of a cast film to the thickness (B) of the central portion in the transverse direction thereof in the range of 2 to 6, biaxially stretching the cast film, and controlling the peak intensity ratio of the biaxially oriented film determined by the laser Raman scattering method in the above-described range. The biaxially oriented polyester film thus produced has a specific orientation in the longitudinal direction, and therefore has great strength in the longitudinal direction and small irregularity in properties such as thickness or birefringence.

Abstract: The specification discloses a thermal stencil paper for mimeograph, having a uniform shape of pores and well-balanced retainability and permeability of printing ink. Thermal stencil paper for mimeograph formed by laminating a porous support member comprising polyester fibers on one surface of a polyester film, characterized in that the porous support member forms a reticulate body having a fusing point at which the fibers are fused to one another, a film which straddles the fibers, and which has a thickness smaller than an average fiber diameter, being formed at some of the fusing points in the reticulate body. Since such thermal stencil paper for mimeograph is provided, the printed matter obtained by a mimeograph using this stencil paper has a high quality of image, and set-off does not occur. Such printed matter is highly convenient to transport.
