ABSTRACT:
The invention relates to a cast resin mixture for bonding substantially sheet-shaped elements, such as glass pane or the like, with a content of at least one non-functionalized acrylic and/or methacrylic ester and at least one functionalized alkyl ester of (meth)acrylic acid, optionally at least one plasticizer, optionally at least one cross-linking agent, optionally at least one primer and optionally at least one polymerization initiator. To improve this cast resin mixture in versatility of use and ease of handling, and to allow glass panes and the like to be bonded to one another reliably and durably, while optionally embedding function elements the acrylic and/or methacrylic ester(s) comprise(s) at least one constituent from the following group: all branched and unbranched saturated aliphatic (meth)acrylic esters, in particular methyl-, ethyl-, n-propyl-, iso-propyl-, n-butyl-, iso-butyl-, sec-butyl-, tert-butyl- and 2-ethyl-1-hexyl-(meth)acrylic esters. At least one functionalized alkyl ester of acrylic or methacrylic acid in the ester group includes at least one hydroxy- or amino- and/or epoxy-function, where the alkyl chains are saturated branched or saturated unbranched.
