POLYIMIDE/METAL LAMINATE, SUBSTRATE FOR ELECTRIC/ ELECTRONIC EQUIPMENT, SUBSTRATE FOR MAGNETIC RECORDING, SUBSTRATE FOR SOLAR CELL, COATING FILM OF SPACE VOYAGE HARDWARE AND FILM-LIKE RESISTOR

摘要

PROBLEM TO BE SOLVED: To improve an adhesive strength after exposure with a high temperature and high humidity environment as an environmental resistance by laminating a polyimide film containing a titanium element and a metal layer in a polyimide/metal laminate. SOLUTION: The polyimide/metal laminate is obtained by directly laminating a metal layer on a polyimide film obtained by cyclodehydrating a polyamic acid containing a pyromellitic anhydride, 4,4-diaminodiphenylether as main components through an epoxy, nylon, acrylic, imide or their mixture adhesive by a method such as a vacuum vapor depositing method, a sputtering method, a wet plating method or the like. Thus, an electric equipment circuit can be operated without impairing a function even in a severe environment having a high temperature and a high humidity and excellent adhesive strength after exposure with the high temperature and high humidity as an environmental resistance.
