  The present disclosure relates to a solvent-containing dry film and a method for applying a dry film on a substrate. The dry film includes a carrier and a resin layer. The resin layer contains a resin composition and a solvent and the solvent is present in a total amount of at least 5 wt % based on the total weight of the resin layer. The dry film of the present invention can be applied onto a substrate without the use of a prior art vacuum lamination apparatus. The application process is simple and is more cost-efficient than the prior art techniques.
