HOTMELT ADHESIVE FOR BONDING DVDS

摘要

The invention relates to hot-melt adhesives with a hot-melt viscosity of over 100,000 mPas at 160 ~C. Said adhesives are suitable for gluing (5) substrate halves (2, 3) during the production of digital versatile discs (DVD) exhibiting considerable procedural advantages in comparison with known UV hardening adhesives. In a pigmented embodiment, said adhesives combine the following three functions: they enable adhesive bonding, provide anticorrosion protection of the metal reflecting layer (4) and form a covering background for a printed pictorial layer (6).
