Claims
- 1. A process for the production of a flexible laminate, the process consisting essentially of applying to a surface of a flexible substrate a curable composition in fluid form and comprising a plastics material as a pattern which can provide a desired image or imaging effect, positioning a metal foil bearing a holographic image and having a layer of plastics size, with the size layer overlying the pattern while the composition remains fluid, applying to the combination heat and pressure at a level and for a time sufficient to adhere the foil to the substrate via the plastics material but insufficient to destroy the holographic effect, and thereafter removing excess foil not adhered to the substrate to expose the desired image or imaging effect.
- 2. A process according to claim 1, wherein the composition is applied by silk screen printing.
- 3. A process according to claim 1, wherein the composition comprises a plastics material suspended in plasticiser.
- 4. A process according to claim 1, wherein the plastics material is PVC.
- 5. A process according to claim 3, wherein the plasticiser is a plastisol ink.
- 6. A process according to claim 1, wherein the metal foil bearing the holographic image is an aluminium foil.
- 7. A process according to claim 1, wherein the foil is a hot stamping foil bearing a holographic pattern.
- 8. A process according to claim 1, wherein the size of the foil is a polyvinyl chloride.
- 9. A process according to claim 2, wherein the foil includes a release layer on that surface of the metal foil which does not carry the layer of plastics size.
- 10. A process according to claim 9, wherein the release layer is removed after treatment and before the holographic effect is required.
- 11. A process according to claim 1, wherein the flexible substrate is a woven or non-woven web.
- 12. A process according to claim 11, wherein the flexible substrate is a fabric.
- 13. A process according to claim 12, wherein the fabric is a natural fabric.
- 14. A process according to claim 1, wherein the substrate is one which is not only flexible but also stretchable.
- 15. A process according to claim 1, wherein the foil and substrate are fed to a laminating station at which heat and pressure can be brought to bear on their combination.
- 16. A process according to claim 15, wherein the feeding to the laminating station is on a continuous or batch basis.
- 17. A process according to claim 1, wherein the foil and the substrate are supplied continuously or intermittently from rollers on which they are stored.
- 18. A process according to claim 1, wherein the foil and substrate are brought together between at least two rollers.
- 19. A process according to claim 1, wherein the foil and substrate are brought together in a heated press which comprises upper and lower heated plates which can be brought together under pressure.
- 20. A process according to claim 1, wherein the temperature conditions are from about 100.degree. C. to about 110.degree. C.
- 21. A process according to claim 1, wherein the temperature is about 100.degree. C.
- 22. A process according to claim 1, wherein the pressure is at least about 200 gm/cm.sup.2.
- 23. A process according to claim 22, wherein the pressure is from about 200 gm/cm.sup.2 to about 210 gm/cm.sup.2.
- 24. A process according to claim 1 wherein the dwell time during which the temperature and pressure conditions apply is from about 20 to about 60 seconds.
- 25. A process for the production of a flexible laminate, comprising:
- providing a metal foil sheet having opposite surfaces, one of the surface bearing a preexisting holographic image thereon such that the metal foil sheet having the holographic image thereon has a given degree of flexibility, the opposite surface having a layer of substantially flexible plastics size applied thereto;
- providing a substantially flexible substrate having an exposed surface thereon;
- applying to the exposed surface on the substrate a curable composition in fluid from and comprising a plastics material as a pattern which can provide a desired pattern;
- forming a hologram/substrate combination by:
- positioning directly on the exposed surface having the curable composition the surface of the metal foil sheet having the layer of plastics size applied thereto with the layer of plastics size overlying the pattern while the curable composition remains fluid,
- applying to the hologram/substrate combination heat and pressure at a level and for a time sufficient to adhere the foil to the substrate via the plastics material but insufficient to destroy or diminish the holographic image; and thereafter
- removing excess foil not adhered to the substrate to expose the desired pattern;
- whereby the heated and pressed combination yields a hologram joined to the substrate such that the combination has a flexibility which is substantially the same as the flexibility of the substrate.
