The present invention provides a primer composition for an insulating film and a method for producing an insulating film using the primer composition. Specifically, in the primer composition for an insulating film according to the present invention, a chelate compound, an epoxy resin, and an inorganic compatibilizer having a size of 60 nm to 100 nm are included. The insulating film having the primer composition includes a step of forming a primer layer on an insulating layer, a step of removing a part of the surface of the primer layer to expose the inorganic coordinator, and the step of removing the exposed inorganic compatibilizer, The surface of the substrate is roughened. By using this, it is possible to make a micro-wiring and can exhibit an effect of high peel strength. |
