Estimating the term…
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.
An anti-static-treated film material comprising an electro-conductive layer on a plastic material, wherein the electro-conductive layer comprises metal oxide particles in an amount of 1 to 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 is between 8.times.10.sup.5 and 1.times.10.sup.20 .OMEGA. at 20 Hz.
