Abstract

Abstract A hot stamping method enables the formation of very sharp edges and profiles of characters/numerals, patterns and the like upon a surface of a base plate. This method comprises a masking step making certain characters, numerals and patterns formed by a masking layer upon a surface of a base plate; a step of placing a foil sheet having an adhesive layer upon a surface of the masking layer and a surface of the base plate, and transferring a foil of the foil sheet to the surface of the base plate by means of heat and pressure; and a step of leaving the transferred foil upon the surface of the base plate and releasing the masking layer and the foil transferred to the surface thereof from the base plate.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 156 words
A hot stamping method comprising: a masking step in which certain characters, numerals and patterns formed by a resinous masking layer are printed upon a surface of a base plate, said masking layer being made of a material which is non-adhesive to the surface of the base plate; a step of placing a foil sheet, comprising a foil layer having an adhesive layer and a backing, upon a surface of the masking layer and a surface of the base plate, and transferring said foil from said backing of the foil sheet to the surface of the base plate by means of heat and pressure; and a step of leaving the transferred foil from the backing upon the surface of the base plate and releasing the masking layer from the surface of the base plate to the overlying foil layer of the foil sheet, leaving portions of the foil in contact with the surface of the base.
Claim 2
Dependent Claim 156 words
A hot stamping method comprising: a masking step in which certain characters, numerals and patterns formed by a resinous masking layer are printed upon a surface of a base plate, said masking layer being made of a material which is non-adhesive to the surface of the base plate; a step of placing a foil sheet, comprising a foil layer having an adhesive layer and a backing, upon a surface of the masking layer and a surface of the base plate, and transferring said foil from said backing of the foil sheet to the surface of the base plate by means of heat and pressure; and a step of leaving the transferred foil from the backing upon the surface of the base plate and releasing the masking layer from the surface of the base plate to the overlying foil layer of the foil sheet, leaving portions of the foil in contact with the surface of the base.
Claim 3
Dependent Claim 26 words
