Abstract
The present invention relates to a laminate structure comprising an adhesive polymeric interlayer (API) that comprises discrete zones. Such discrete zones are located at the interface of the API and the glass substrate. Generally, the discrete zones comprise two sets of discrete zones, debonding and adhesive. These zones allow for a unique combination of modified API-glass debonding, laminate toughness, and laminate durability. Various spatial patterns and densities of debonding are described, as well as the resulting material properties.
