    摘要: Disclosed is a polyimide film which is free from coarse particles caused by aggregation of a filler, therefore, can avoid abnormal electrical discharge during a discharge treatment, repelling during application of an adhesive, and the like. Also disclosed is a method for production of the polyimide film. The method for production of the polyimide film is characterized by using an organic solvent solution containing an inorganic filling material and a first polyamic acid, wherein the organic solvent solution containing the first polyamic acid is prepared by a process comprising the steps of: 1) preparing a dispersion solution which contains the inorganic filling material and a second polyamic acid and has a viscosity of 50 to 500 poises; 2) filtering the dispersion solution; 3) mixing a prepolymer solution containing the first polyamic acid in the process of being polymerized and having a viscosity of 100 poises or lower with the filtered dispersion solution; and 4) increasing the viscosity of the mixed solution to a level ranging from 1000 to 6000 poises.

    摘要: Disclosed is a flexible metal clad laminate plate with good appearance which can be manufactured by a metalizing method such as evaporation coating, sputtering or plating. The flexible metal clad laminate plate has a polyimide film. The polyamide film is produced by reacting an aromatic diamine with an aromatic acid dianhydride to produce a polyamide acid and then imidizing the polyamide. The polyamide film has (A) an inflexion point of the storage modulus falling within the range from 270 to 340° C., (B) the peak top of tan δ; (which is a value given by dividing the loss modulus by the storage modulus) falling within the range from 320 to 410° C., (C) the storage modulus at 400° C. falling within the range from 0.5 to 1.5 GPa, and (D) the storage modulus α1 (GPa) at the inflexion point and the storage modulus α2 (GPa) at 400° C. both falling within the range satisfying Formula (1) below 85≧{(α1−α2)/α1}×100≧70.  (Formula 1)
