The alkaline reserve is intended to neutralize future acidic components that may otherwise accumulate. As cellulosic materials are very sensitive to acid degradation, an alkaline reserve is sometimes added to archival papers and treated papers to minimize acid produced embrittlement, yellowing, and deterioration.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31436720"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31306090"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14061002"> <skos:prefLabel xml:lang="es">reserva alcalina</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9829421"> <skos:prefLabel xml:lang="ca">reserva alcalina</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:26:21</dct:created>  </skos:Concept></rdf:RDF>
