  • Photographic support and photographic material
    Patent number: 6132951
    Abstract: Provided is a photographic support which is excellent in mechanical strength and is less liable to get into roll set curl and which is excellent in cutting property and flatness, and a photographic material using the same. The support for photographic material comprises a polyester film, wherein the polyester film comprises two kinds of polyester resins, each has intrinsic viscosity of 0.2-1.2, and a difference in the intrinsic viscosity between the polyester resins is 0.1-1.0.

  • Plastic film having an improved anti-static property
    Patent number: 6066442
    Abstract: An anti-static-treated film material having an electro-conductive layer is disclosed. The film material contains at least one selected from conductive particles and semi-conductive particles at an amount between 1 and 50 vol. % with respect to said electro-conductive layer and polymer particles having an average particle diameter of 0.01 to 5 .mu.m, and the absolute value of impedance of said film material under frequency at 20 Hz is between 4.times.10.sup.5 and 1.times.10.sup.20 .OMEGA.. The film material is suitably used as a support of asilver halide light sensitive material.
