Abstract:
1. A method of manufacturing an antistatic film comprising the steps of: preparing a plurality of sample films with electrostatic charges (V) and surface resistivity (R), at least one of said electrostatic charges (V) and surface resistivity (R) differing stepwise from one another; making a simulation of static trouble outbreaks by running said sample films through a given simulation equipment under specified conditions; expressing electrostatic charges (V) and surface resistivity (R) of said sample films that cause static troubles in said simulation of static troubles in an orthogonal R-V coordinate diagram; defining a proper range of electrostatic property for said antistatic film on said R-V orthogonal coordinate diagram that excludes electrostatic charges (V) and surface resistivity (R) of said sample films that cause unacceptable static troubles; and designing and manufacturing said antistatic film so as to satisfy said proper range of electrostatic property.
