Title:
【発明の名称】光透過性積層パネル及びその耐衝撃性を改良する方法
Document Type and Number:
Japanese Patent JPH11512695
Kind Code:
A
Abstract:
A light-transmitting laminated panel having increased resistance to impact-induced rupture sequentially includes: a) a glass layer, b) an optically clear layer of a plasticized polyvinyl butyral matrix containing discrete particles of crosslinked polyvinyl butyral integrally randomly dispersed throughout the matrix which enhance the impact-resistance of the panel and are visually indistinguishable from the matrix polyvinyl butyral, and c) another glass layer, the laminated panel at a specific pummel adhesion having greater mean break height than that of a laminated panel containing layers a), b) and c) but without the impact-resistance-enhancing particles of crosslinked polyvinyl butyral in layer b). An amount up to 40 weight % of the particles is incorporated into the matrix polyvinyl butyral before preparing the laminated panel.
