Abstract
A laminated glazing is disclosed. Among other things, the laminated glazing includes a first glass sheet; a first interlayer; a photopolymer film; a second interlayer; and a second glass sheet, wherein the total thickness of the second glass sheet and the second interlayer is from 0.5 mm to 2.5 mm.
Claims20
A laminated glazing, comprising:
- a first glass sheet;
- a first interlayer;
- a photopolymer film, the photopolymer film comprising a volume hologram;
- a second interlayer;
- and
- a second glass sheet,
- wherein a total thickness of the second glass sheet and the second interlayer is from 0.5 mm to 2.5 mm, and
- wherein the first glass sheet and the second glass sheet are the only glass components of the laminated glazing and each of the first interlayer, the photopolymer film, and the second interlayer are disposed between the first glass sheet and the second glass sheet.

A method for preparing a glazing, comprising:
- laminating a first glass sheet, a first interlayer, a photopolymer film, a second interlayer, and a second glass sheet to provide a laminated glazing, the photopolymer film comprising a material configured to record a volume hologram;
- and
- applying a reactive light to the photopolymer film through a master holographic film, wherein the reactive light transmits through the master holographic film, the second glass sheet, and the second interlayer and records a volume hologram in the photopolymer film;
- wherein the first glass sheet and the second glass sheet are the only glass components of the laminated glazing and each of the first interlayer, the photopolymer film, and the second interlayer are disposed between the first glass sheet and the second glass sheet.
