Beschreibung
Zusammenfassung:	The invention relates to a hot-melt adhesive for producing digital versatile disks (DVD), said adhesive containing between 2 and 15 wt. % of base-modified pigments which are specifically selected from the group of titanium dioxide, silicon dioxide, aluminium oxide, barium sulfate, and zinc sulfate. Said pigments are treated on the surface by means of specific metallic salts and have an anti-corrosive effect, in addition to their white colouring. Said hot-melt adhesives are used in the production of DVDs, for the adherence of individual disk blanks in order to form a complete DVD, and provide the reflecting layer with improved protection against corrosion, thus increasing the service life of the DVD.
