Patent Application
20060234067
The present invention relates to a laser gilding film with a laser pattern, and more particularly to a laser gilding film containing a curing coating and manufacture thereof.
The U.S. patent Pub. No. 20040241404 discloses a paper with holographic pattern and manufacture of it, in which a separation type metallized holographic image is caused to transfer from a mother film to a paper by means of illumination combination of UV resin and UV light. Because an UV illumination facility is needed according to the patent application to combine a metallized holographic image onto a paper, the application of the gilding film with the metallized holographic image is limited.
The U.S. Pat. No. 5,939,177 discloses a holographically transferable image in which a heating and pressuring is used to transfer a metallized holographic image spread with an adhesive layer onto a package paper to cause the package paper to have a holographic image thereon. The metallized holographic image stuck on the package paper according to the patent has no protective film; an extra work must be done to generate a protective film, this will increase a working hour.
The U.S. Pat. No. 6,558,788 disclosed a holographic transfer film. A holographic image is disposed at the outer layer of a transfer film and a metal film is electroplated on the outer layer with the holographic image. A glue or adhesive is spread on a carrier to stick a metal film with a holographic image to cause the metal film with the holographic image to be transferred from the transfer film to the carrier. The metallized holographic image stuck on the package paper according to the patent has no protective film too; an extra work must be done to generate a protective film, this will increase a working hour.

A separation type layer 12 needs to be spread between the plastic film 11 and the laser pattern layer 13 when the laser gilding film 10 mentioned above is manufactured, the manufacturing processes are rather complex and the manufacturing materials, time and cost are rather consumed.
For providing a laser gilding film containing a curing coating and manufacture thereof and enabling the manufacturing processes to be simplified so as to save the production time and cost, the present invention is proposed.
The main object of the present invention is to provide a laser gilding film containing a curing coating and manufacture thereof, enabling the manufacturing processes to be simplified and the production time and cost to be rather saved.
Another object of the present invention is to provide a laser gilding film containing a curing coating and manufacture thereof, capable of simplifying the structure and saving the materials.
The present invention can be more fully understood by reference to the following description and accompanying drawings, in which:

A material of the curing coating layer 32 can be a UV curing coating or electron beam curing coating. The mold 40 mentioned above can be a holographic laser film or holographic laser impressing wheel. After the curing coating layer 32 is caused to stick on the mold 40 and illuminated with UV light or an electron beam to solidify the curing coating layer 32, and it is then separated from the mold 40. The electroplated metal layer 33 is formed by processing vacuum electroplating with a metal material such as aluminum or zinc sulfide.
Please refer to
A separation type layer is unnecessary to be spread between the plastic film 31 and the curing coating layer 32 of the laser gilding film containing the curing coating layer according to the present invention.
The laser lines 41 on the mold 40 of the present invention can be the lines of characters or/and a pattern to allow the gilding film to have the image of characters or/and a pattern. The laser lines 41 are also allowed not to appear on the mold 40 according to the present invention to cause the gilding film have no image.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
