20100040874 | FILM FOR METAL FILM TRANSFER, METHOD FOR TRANSFERRING METAL FILM AND METHOD FOR MANUFACTURING CIRCUIT BOARD - Films for metal film transfer, which contain (a) a support layer, (b) a release layer formed on the support layer, which is comprised of one or more kinds of water-soluble polymers selected from a water-soluble cellulose resin, a water-soluble polyester resin, and a water-soluble acrylic resin, and (c) a metal film layer formed on the release layer, show superior transferability of the metal film layer. Such films are useful for efficiently producing circuit boards by laminating the film for metal film transfer on a curable resin composition layer on a substrate such that the metal film layer is in contact with a surface of the curable resin composition layer, curing the curable resin composition layer, detaching the support layer, and removing the release layer on the metal film layer by dissolving the release layer in an aqueous solution. | 02-18-2010 |

20100044078 | PROCESS FOR PRODUCING CIRCUIT BOARD - Producing a circuit board, by laminating, on a substrate, an adhesive film with a metal film, which comprises a water-soluble polymer release layer, a metal film layer and a curable resin composition layer, which are formed in this order on a support layer, and has a release property enabling detachment of said water-soluble polymer release layer from the support layer after curing of the curable resin composition layer, such that the curable resin composition layer contacts the substrate; curing the curable resin composition layer; detaching the support layer, and removing the water-soluble polymer release layer present on the metal film layer by dissolving the release layer in an aqueous solution, efficiently forms an insulating layer and a metal film layer superior in adhesiveness to the insulating layer and in uniformity. By this method, a metal film layer having high adhesiveness and high property uniformity can be formed on the surface without the need for roughening the surface of an insulating layer with an oxidant such as alkaline potassium permanganate solution and the like. Thus, etching for circuit formation can be performed under milder conditions, which in turn provides a superior effect on micro wiring on circuit boards such as multi-layer printed wiring boards, flexible printed wiring boards, and the like. | 02-25-2010 |
