Abstract: A filmy coil comprising a metal conductive layer of the thin-line type having a spiral pattern on one side or both sides of an optional insulating substrate film or sheet, characterized in that the interval between each adjacent metal conductive line is smaller than the thickness of the metal conductive layer, and a manufacturing method for such a filmy coil characterized in that a photoresist layer, the patterns of both sides thereof being mirror images, is made up on both sides of the metal conductive foil or sheet, then both sides of the photoresist layer are etched to the depth of 30 to 40% of the thickness of the metal conductive foil or sheet by means of chemical etching, one side of the metal conductive foil or sheet is coated by an isolated resin coat or laminated with an isolated substrate film or sheet layer, the other side of said photoresist layer is etched also by means of chemical etching until the etching grooves on both sides pass through to be connected with each other, to produce a filmy coi

Abstract: A transfer material comprises a carrier sheet, a stripping layer releasably disposed on discrete spaced-apart portions of the upper surface of said carrier sheet, a color-containing design layer covering depressed portions formed by said stripping layer on the surface of said carrier sheet, said design layer having adequate adhesive properties with respect to said carrier sheet and to an innermost layer of a color-containing designed laminate assembly, thereby providing tearing in the thickness of said design layer in the process of transferring, layers of color-containing designed laminate assembly being adhered together, and a thoroughly coated outermost layer of said designed laminate assembly including heat sensitive adhesive materials.
