NOVELTY - A transfer pattern is produced by forming one or more types of notches on same plane on surface of a mandrel for molding. A smooth plating is given to surface of the notches so that the sloped curved surface of smooth plating film touches the flat surface of the notches.    USE - For transfer film (claimed) used in the production of diffused reflection board of solar battery, diffused reflection type liquid crystal display.    ADVANTAGE - Diffused reflection board which has favorable reflective characteristics is manufactured efficiently. The reflective characteristics of the reflection board can be freely controlled by setting the rough surface of the transfer film to required roughness.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (i) Manufacture of transfer pattern which involves forming one or more types of notches adjacently on surface of a mandrel and performing a smooth plating process on the notches so that flat surface of notches touches the sloping curved surface of plating film; (ii) Concavo-convex film on which the transfer pattern is transferred, by pushing the transfer pattern on the undercoat provided to a transfer film or base film; (iii) Diffused reflection board which comprises a reflecting film provided to rough surface of concavo-convex film; (iv) Transfer film formed by laminating a thin film layer to the rough surface of a concavo-convex film, used as temporary support. The surface of thin film layer not laminated to support is used as adhesive surface on a transferred substrate; and (iv) Manufacture of diffused reflection board which involves providing the transfer film on a transferred substrate (permanent substrate) so that thin film layer may face the substrate and removing the temporary substrate followed by forming a reflecting film on concavo-convex surface of thin film layer.    DESCRIPTION OF DRAWING(S) - The figure shows sectional drawing of the manufacturing process. (Drawing includes non-English language text).
