Beschreibung
Zusammenfassung:	This invention relates to a laminated glazing unit, comprising sequentially: a first glass sheet; an adhesive layer including a polymeric material, said adhesive layer having a first refractive index; a support layer including a plasticized vinyl chloride polymer having a number average molecular weight of at least 30,000, said support layer having a second refractive index and a total plasticizer concentration of between 20 phr to 60 phr; a second adhesive layer including a polymeric material; and a second glass sheet; wherein said first and said second refractive indices differ by no more than 0.05.
