Abstract
The invention relates to the use of a building composition marker comprising at least one alpha-amino acid, alpha-amino acid salt or a mixture thereof in a building composition. The invention also relates to a building composition comprising such a building composition marker, and to a process for producing the building composition. The invention further relates to a building composition marker comprising at least one alpha-amino acid, alpha-amino acid salt or mixture thereof, and one or more components selected from:—vinyl ester homopolymers, vinyl ester copolymers comprising one or more vinyl ester units and one or more monomer units from the group selected from olefins, vinylaromatics, vinyl halides, acrylic esters, methacrylic esters, monoesters or diesters of fumaric and/or maleic acid, or silicon-functional monomers; —(meth)acrylic ester homopolymers, (meth)acrylic ester copolymers comprising one or more (meth)acrylic ester units and one or more monomer units from the group of vinylaromatics, vinyl halides, monoesters or diesters of fumaric and/or maleic acid, or silicon-functional monomers; —homopolymers or copolymers of dienes and also of olefins, diene copolymers comprisin…
