Abstract

A method of manufacturing a hot-stamped decal includes step A: preparing a metalized polyester film including a metalized layer disposed on a top surface thereof, a clear polyester sheet disposed to an under side of the metalized layer, an adhesive layer disposed to an under side of the clear polyester sheet and a release sheet disposed to an under side of the adhesive layer, step B: applying a printing process on the metalized layer to form a mark thereon composed of a printed ink layer, step C: preparing an alkaline corrosive solution, step D: flushing the top surface of the metalized layer with the alkaline solution composed of water and NaOH to the top surface of the metalized layer to corrode the metalized layer not covered by the printing ink layer, step E: flushing the top surface of the metalized layer with water and step F: drying the hot-stamped decal.

Claims

1. A method of manufacturing a hot-stamped decal and comprising the following steps:

A. preparing a metalized polyester film comprising a metalized layer disposed on a top surface thereof, a clear polyester sheet disposed to an under side of the metalized layer, an adhesive layer disposed to an under side of the clear polyester sheet and a release sheet disposed to an under side of the adhesive layer;

B. applying a printing process on the metalized layer to form a mark thereon composed of a printed ink layer;

C. preparing an alkaline corrosive solution;

D. flushing the top surface of the metalized layer with the alkaline solution composed of water and NaOH to the top surface of the metalized layer to corrode the metalized layer not covered by the printing ink layer;

E. flushing the top surface of the metalized layer with water; and

F. drying the hot-stamped decal.

2. The method as claimed in claim 1 wherein the alkaline solution is composed of 75% water and 25% NaOH.

3. The method as claimed in claim 2 wherein the solution used in step d has a surrounding temperature of 35 degrees Celsius.
