FIELD: process engineering.
SUBSTANCE: invention relates to laminated sheet. Laminated sheet comprises glass fibers of woven and nonwoven materials fixed by binder and fluorine-containing film laid one onto another. Said binder comprises copolymer A with recurrent links a1 and a2. Recurrent links a1 represent, at least, one fluorine-containing monomer selected from group consisting of tetrafluoroethylene, chlorotrifluoroethylene and hexafluoropropylene. Recurrent links a2 represent, at least, one monomer not containing fluorine and selected from the group consisting of vinyl ether, vinyl ester, isopropenyl ether, isopropenyl ester, allyl ether and allyl ester.
EFFECT: higher translucence, longer life.
