Holographic films contain a copolymer binder having the following formula: (M)w(VAc)x(VOH)y(CTFE)z wherein M is a fluoromonomer; VAc is vinyl acetate; VOH is vinyl alcohol; and CTFE is chlorotrifluoroethylene; and wherein w, x, y, and z are percentages by weight; w is 5 to 22%, x is 50 to 75%, y is 3 to 8%, and z is 15 to 30% with the copolymer containing 3-35% by weight fluorine. These imaged films are particularly suited for lamination to glass in head-up display applications. |
