  • Patent number: 9822226
    Abstract: An object of the present invention is to provide: a dry film comprising a resin layer which has excellent detachability from a carrier film and in which cracking and powdering are inhibited; and a printed wiring board comprising a cured article obtained by curing the dry film. The dry film comprises a resin layer containing a thermosetting resin component, a filler and at least two solvents, wherein the at least two solvents both have a boiling point of 100° C. or higher and the boiling points of the at least two solvents are different by not less than 5° C.

  • Patent number: 9796810
    Abstract: An object of the present invention is to provide: a heat-curable composition capable of yielding a cured article in which crack generation during a heating-cooling cycle can be inhibited; a dry film thereof; and a printed wiring board comprising the cured article. The heat-curable composition is characterized by comprising a semisolid or a solid epoxy compound and a curing accelerator that is made miscible with the epoxy compound when heated at 130 to 220° C. The dry film comprises a resin layer formed from this heat-curable composition, and the printed wiring board comprises a cured article obtained from the heat-curable composition or the dry film.
