I've been doing some test with this polymer to find something to work as and adhesive , and came across one thing that works, 3d uv resin
the hologram is shot at 532nm for test, this test polymer was coated on both sides with uv resin

the layer hast to be thin and cured in sun light or uv quickly after lamentation,
If you delay and let the uv resin time to soak in the polymer it will swell up the fringes and shift to red.

the way I did it is use a piece scotch tape to tape the top of the hologram to the glass,
then bend it back, and put a bead of uv resin along the edge of the tape glass and polymer then squeegee it, then take a put it out into the sun.
then when its cured you can remove the coversheet and then ether uv glass to the top or paint thin coat on top and cure in sun light

trying some other thing but will post them later

Also tested 3m 300LSE it shifts 1 wave length so if you shoot in red replay will be in green
if shot in full color it shifts replay angle 45% :o

Potentially useful info. Thank you. Can you be more specific about 3D UV resin? Manufacturer, item #, cover sheet you removed?

the resin I used is Voxedlab Standard Photopolymer Resin Transparent , its the type use for 3d uv resin printers , what I did is make the hologram on a glass plate then transfer it to another piece of glass and glued it with 3d resin then after cured i remove top cover on polymer and painted with uv resin and cured... many possibilities

so this means some uv resins will work, I do it really fast post process and then spend time in cleanup... its a idea that show some promise
