Abstract:
     The composite film with reflecting hologram and angular color changing diagram consists of reflecting holographic layer and angular color changing information diagram layer connected via connecting layer. The reflecting holographic layer consists of surface covering layer, protecting layer, optical polymer information record layer and reinforcing layer compounded successively. The angular color changing information diagram layer consists of isolating layer, light changing function layer of angular color changing material, isolating layer, coloring layer and adhering layer compounded successively. The preparation process of the composite film includes the following steps: preparing reflecting holographic layer and the angular color changing layer separately, laminating or hot compounding the two, and optical copying. The present invention has raised anti-fake effect and may be used in anti-fake widely.
