Abstract
Abstract A stamping foil which comprises a flexible supporting web, a lubricating layer provided on substantially whole one surface of the supporting web, a colored water-resistant resinous layer having a desired pattern and a metal deposition layer having a desired pattern provided on the lubricating layer, and an adhesive layer provided in a manner that all of the exposed surfaces of the lubricating layer, of the colored water-resistant resinous layer and/or of the metal deposition layer are covered by the adhesive layer. The stamping foil has an advantage that even a complicated combined pattern of the colored layer and the metal deposition layer can be obtained by a single operation with ease and low cost.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
a method for making a stamping foil comprising: (a) spreading a flexible supporting web; (b) applying a transparent and colorless lubricant layer over said flexible supporting web; (c) applying a colored resinous layer over portions of said lubricant layer; (d) applying a water-soluble coating layer over at least a part of one or both of said lubricant layer and said resinous layer so that the water-soluble coating layer is formed on ares corresponding to subsequent portions to be removed; (e) depositing a layer of metal over essentially all of the exposed sufaces; (f) washing the surface with an aqueous solution or water to remove metal coated upon the water-soluble coating layer; and (g) applying a layer of adhesive over substantially the whole surface.
Claim 2
Independent Claim
123 words
a method for making a stamping foil comprising: (a) spreading a flexible supporting web; (b) applying a transparent and colorless lubricant layer over said flexible supporting web; (c) applying a colored resinous layer over portions of said lubricant layer; (d) applying a water-soluble coating layer over at least a part of one or both of said lubricant layer and said resinous layer so that the water-soluble coating layer is formed on ares corresponding to subsequent portions to be removed; (e) depositing a layer of metal over essentially all of the exposed sufaces; (f) washing the surface with an aqueous solution or water to remove metal coated upon the water-soluble coating layer; and (g) applying a layer of adhesive over substantially the whole surface.
Claim 3
Dependent Claim
21 words
