Abstract

The invention relates to a one-step method for producing laminated safety glass panes. Said laminated safety glass panes consists of at least two glass panes and a plasticized, partially acetalized polyvinyl alcohol interlayer. According to the non--autoclave method, a plasticized, partially acetalized polyvinyl alcohol film with a roughness R z between 70 µm and 150 µm is used.
