Abstract

Det er beskrevet oksidative sammensetninger og fremgangsmåter som bevarer og fremmer glansen og forbedrer fargen på masse eller papir når anvendt under forskjellige stadier av papirfremstillingsprosessen er identifisert. Den oksidative sammensetningen og fremgangsmåten opprettholder og/eller fremmer glans, forebygger gulning, og fremmer utførelsen av papirprodukter. Anvendt i kombinasjon med optiske glansmidler og/eller chelatdannere produserer de oksidative midlene en synergistisk virkning som ikke tidligere er identifisert i papirprosessen.
