ABSTRACT:
Disclosed is a process for configuring a hologram (30) onto a final laminate (38) incorporating the hologram (30), including a car windshield or an aircraft canopy. The process includes first developing the hologram (30) on a process substrate (22). Intermediate the hologram (30) and the process substrate (22) is a thermoplastic layer (24). After the hologram (30) has been developed, the hologram laminate (20) including the process substrate (22), thermoplastic layer (24), and hologram (30) is applied to a first final laminate layer (34) by means of an adhesive (32) such that the hologram (30) is facing the first final laminate layer (34). Once this step is completed heat is applied to the hologram laminate (20) to melt the thermoplastic layer (24), thus removing the process substrate (22). Therefore, a second final laminate layer (40) can be applied to the opposite side of the hologram (30) without any drawbacks from the thickness of any additional support layers in the final laminate (38).
