Poly(vinyl acetal) sheets exhibiting enhanced adhesion to inorganic surfaces

摘要

Resin layers and interlayers exhibiting enhanced adhesion to inorganic surfaces, such as glass, are provided. In some cases, the layers and interlayers may comprise at least one adhesion stabilizing agent for improving adhesion to various surfaces, even in the presence of moisture. Such layers and interlayers may be useful, for example, in multiple layer panels, such as, for example, safety glass used in automotive and architectural applications.
