Abstract
A printable, pressure-sensitive adhesive ("PSA") tape, particularly a self-wound tape, which comprises a polyester film substrate, a rubber base prime coat and an adhesive which can be fire-retardant. The PSA tape has high adhesive properties and a novel release mechanism which does not use any conventional release agents.
Claims15
A ternary printable, pressure-sensitive adhesive tape not having a release agent or coating consisting essentially of:
- a polyester film substrate having first and second opposing sides;
- a pressure-sensitive adhesive layer disposed on said first side;
- and
- a rubber base prime coat capable of accepting printing ink being disposed on said second side of said substrate, which prime coat comes in direct contact with said adhesive when the tape is wound up on itself in roll form and which releases said adhesive without the use of a separate release coating;
- said prime coat comprising natural rubber crosslinked by an isocyanate.
