Abstract (en)

[origin: WO2022132417A1] The present invention relates to a laminate structure comprising at least one glass substrate and an adhesive polymeric interlayer (API) that comprises cohesive debonding zones that are substantially discrete and/or substantially continuous in their layout. Such debonding zones are located preferably within the 10% thickness of API from the interface of said API and the glass substrate. 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.
