SECURITY DEVICE COMPONENTS AND METHODS OF MANUFACTURE THEREOF |
| 摘要 |
A method of manufacturing a security device component includes: providing a photosensitive film including a diazonium compound which decomposes upon exposure to radiation of a predetermined wavelength; providing a dye coupler film comprising one or more dye coupler compositions; exposing elements of the photosensitive film to radiation of the predetermined wavelength in accordance with a predetermined pattern; and contacting at least part of the exposed photosensitive film against at least part of the dye coupler film so as to effect at least partial transfer of the one or more dye coupler compositions to the exposed photosensitive film, whereupon unexposed elements of the photosensitive film exhibit one or more colours such that the photosensitive film exhibits a reproduction of the predetermined pattern. |

1. A method of manufacturing a security device component, comprising:
providing a photosensitive film comprising a diazonium compound which decomposes upon exposure to radiation of a predetermined wavelength; providing a dye coupler film comprising one or more dye coupler compositions; exposing elements of the photosensitive film to radiation of the predetermined wavelength in accordance with a predetermined pattern; contacting at least part of the exposed photosensitive film against at least part of the dye coupler film so as to effect at least partial transfer of the one or more dye coupler compositions to the exposed photosensitive film, whereupon unexposed elements of the photosensitive film exhibit one or more colours such that the photosensitive film exhibits a reproduction of the predetermined pattern. |
