Abstract
A composite sheet having the capability of having embossed therein a holographic image or diffraction grating image has a structure of multiple layers including a plastic film carrier, lacquer, metal and, optionally, a lacquer overlay. It may be adhered to a substrate without the necessity of removing the plastic film carrier and may have a holographic image embossed therein during the step of adhering or in a separate operation at a different time and may have printing applied to the layer of metal or to the lacquer overlay.
Claims12
A method for making an article comprising the steps of:
- (a) providing a composite sheet having the capability of receiving embossed therein a holographic image or diffraction grating image, said composite sheet including:
- (i) a plastic film carrier layer,
- (ii) a layer of lacquer,
- (iii) a layer of metal,
- (iv) a lacquer overlay on said layer of metal,
- (b) providing a substrate having a layer of adhesive;
- (c) feeding said substrate and said composite sheet to a pressurizing station with said layer of adhesive facing said plastic film carrier layer, said station having a pair of surfaces;
- (d) subjecting said substrate and said composite sheet to pressure from said surfaces to adhere said composite sheet to said substrate;
- and
- (e) embossing a holographic or diffraction grating image into said lacquer overlay, said layer of metal and at least partially into said layer of lacquer.
A method for making an article comprising the steps of:

- (i) a plastic film carrier layer,
- (ii) a first layer of lacquer,
- (iii) a second layer of lacquer,
- (iv) a layer of metal,
- (v) a layer of lacquer overlay on said layer of metal,
- (b) providing a substrate having a layer of adhesive;
- (c) feeding said substrate and said composite sheet to a pressurizing station with said layer of adhesive facing said plastic film carrier layer, said station having a pair of surfaces;
- (d) subjecting said substrate and said composite sheet to pressure from said surfaces to adhere said composite sheet to said substrate;
- (e) embossing a holographic or diffraction grating image into said lacquer overlay, said layer of metal and at least partially into said second layer of lacquer;
- and
- (f) printing on said lacquer overlay.
