Abstract

A method for the manufacture of a composite laminate assembly that includes decorative, functional, security, reflective, diffractive, holographic elements for liquid transfer onto the surface of a variety of base materials or work piece having a flat or complex three dimensional shape.

First claim

The invention claimed is:

1. A laminate assembly for decorating an object in a hydrographic transfer system, the laminate assembly comprising:
a carrier film configured to be soluble when placed into the hydrographic transfer system;
an optical effect layer configured to provide one or more of an optical effect or a security feature to the object, the effect layer including a relief pattern formed by cracks extending through an entire thickness of the effect layer;
one or more ink layers disposed between the carrier film and the effect layer; and
a coat layer disposed between the one or more ink layers and the optical effect layer, wherein the effect layer includes a relief pattern configured to provide the one or more of the optical effect or the security feature to the object.

2. The laminate assembly of claim 1 , wherein the effect layer is formed from one or more of a metal, a metal alloy, or a high refractive index material.

3. The laminate assembly of claim 1 , wherein the optical effect provided by the effect layer includes one or more of a holographic design or a design that changes color based on a viewing angle.

4. The laminate assembly of claim 1 , wherein the relief pattern in the effect layer provides the one or more of the optical effect or the security feature.

5. The laminate assembly of claim 1 , wherein the effect layer is formed by separate bodies that are laterally separated from each other by the cracks in directions that are parallel to a surface of the effect layer that faces the coat layer.

6. The laminate assembly of claim 1 , wherein the cracks that extend through the entire thickness of the effect layer are microcracks.

7. The laminate assembly of claim 1 , wherein the relief pattern is an embossed pattern in the effect layer.

8. A laminate assembly for transferring decoration onto an object in a hydrographic transfer system, the laminate assembly comprising:
a carrier film configured to be soluble when placed into the hydrographic transfer system;
an optical effect layer configured to provide one or more of an optical effect or a security feature to the object, the effect layer formed by separate bodies that are spaced apart from each other by gaps; and
a coat layer disposed between the carrier layer and the optical effect layer, wherein the effect layer includes a relief pattern configured to provide the one or more of the optical effect or the security feature to the object.

9. The laminate assembly of claim 8 , wherein the effect layer is formed from one or more of a metal, a metal alloy, or a high refractive index material.

10. The laminate assembly of claim 8 , wherein the optical effect provided by the effect layer includes one or more of a holographic design or a design that changes color based on a viewing angle.

11. The laminate assembly of claim 8 , wherein the effect layer includes a relief pattern that provides the one or more of the optical effect or the security feature.

12. The laminate assembly of claim 11 , wherein the relief pattern is defined by the separate bodies that form the effect layer.

13. The laminate assembly of claim 11 , wherein the coat layer is an embossed layer.

14. The laminate assembly of claim 11 , wherein the gaps that separate the separate bodies that form the effect layer are microcracks.

15. The laminate assembly of claim 11 , wherein the relief pattern is an embossed pattern in the effect layer.

16. A laminate assembly for decorating an object in a hydrographic transfer system, the laminate assembly comprising:
a soluble carrier film;
a design layer having a relief pattern formed in a reflective or diffractive layer and providing an optical effect on the object, the reflective or diffractive layer formed by cracks extending through an entire thickness of the reflective or diffractive layer; and
one or more ink layers disposed between the carrier film and the design layer.

17. The laminate assembly of claim 16 , wherein the design layer provides an optical effect design that changes color based on a viewing angle of the object.

18. The laminate assembly of claim 16 , wherein the relief pattern in the design layer is formed by separate bodies that are separated from each other by the cracks in the reflective or diffractive layer spaced apart from each other by gaps.

19. The laminate assembly of claim 18 , wherein the cracks that separate the bodies in the reflective or diffractive layer are spaced apart from each other are microcracks.

20. The laminate assembly of claim 18 , wherein the relief pattern in the design layer is an embossed pattern.
