LAYERED MATERIAL FOR MULTILAYER GLASS AND INTERLAYER FILM FOR MULTILAYER GLASS Russian patent published in 2014 - IPC C03C27/12 B32B17/10 C08J5/18 

FIELD: chemistry.

SUBSTANCE: invention relates to production of layered materials for multilayer glass and can be used as a HUD display which does not deteriorate even when exposed to light. The layered material includes an interlayer film and a retarding element placed between adhesive layers. The film of the multilayer glass contains a thermoplastic resin and a UV absorber. The UV absorber is a benzotriazole compound or a benzophenone compound and at least one compound selected from a group consisting of a malonic ester compound, an oxanilide compound and a triazine compound. Total content of the malonic ester compound, oxanilide compound and triazine compound is not less than 0.8 pts.wt, and total content of the benzotriazole compound or benzophenone compound is not less than 0.8 pts.wt per 100 pts.wt thermoplastic resin. The adhesive layer contains an adhesive, having a glass transition point of -20°C or lower.

EFFECT: layered material has high impact strength.
