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

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; 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 effect layer includes a relief pattern that provides the one or more of the optical effect or the security feature.

5 . The laminate assembly of claim 4 , wherein the relief pattern is defined by separate bodies of the effect layer separated by gaps.

6 . The laminate assembly of claim 4 , wherein the relief pattern is defined by separate bodies of the effect layer separated by microcracks.

7 . The laminate assembly of claim 4 , 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; 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 separate bodies of the effect layer separated by gaps.

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

14 . The laminate assembly of claim 11 , wherein the relief pattern is defined by separate bodies of the effect layer separated by microcracks.

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

16 . A method for manufacturing a laminate assembly for being transferred onto an object in a hydrographic-transfer system, the method comprising:
depositing one or more ink layers above a carrier film configured to be soluble when placed into the hydrographic transfer system; depositing a coat layer above the one or more ink layers; depositing an optical effect layer above the coat layer; and forming a relief pattern in the optical effect layer, the relief pattern configured to provide one or more of an optical effect or a security feature to the object.

17 . The method of claim 16 , wherein forming the relief pattern includes embossing the relief pattern in the optical effect layer.

18 . The method of claim 16 , wherein depositing the effect layer includes depositing one or more of a metal, a metal alloy, or a high refractive index material.

19 . The method of claim 16 , wherein depositing the one or more ink layers includes printing the one or more ink layers using one or more of thermal transfer printing, digital ink jet printing, three dimensional printing, or cross-linking ink in the one or more ink layers.

20 . The method of claim 16 , wherein depositing the effect layer includes vapor depositing one or more metals or metal alloys.
