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).

Abstract: A plastic sheet, preferably of plasticized partial polyvinyl butyral, for a laminated safety glazing, having means dispersed on its surface, preferably comprising a multiplicity of spaced projections, capable of resisting adhesion to a rigid panel, such as glass, of such a glazing when the sheet is laminated to the panel, the area of the sheet surface without such dispersed means having high affinity for adhesion. The projections physically block adhesion of a dispersed area of the sheet to the panel in that the means on the sheet surface have no or weak interfacial adhesion. The multiplicity of space projections also have low or no affinity for adhesion when in blocking contact with each other or with another plasticized partial polyvinyl butyral surface and thereby increase blocking resistance.
