Abstract
This invention relates to labels. In one embodiment the labels comprise a polymer facestock layer, a nano-porous layer underlying the facestock, and an adhesive layer underlying the nano-porous layer. In another embodiment, the labels comprise a polymer facestock layer, a nano-porous layer underlying the facestock, and a metal layer overlying the facestock or underlying the facestock between the facestock and the nano-porous layer. These labels can be bonded to substrates of glass, plastic, or metal using a water based adhesive which is in contact with the nano-porous layer.
Claims49
An adhesive label comprising:
- (A) a polymer facestock having an upper surface and a lower surface,
- (B) a nano-porous layer having an upper surface and a lower surface wherein the upper surface of the nano-porous layer underlies the facestock, and the nano-porous layer contains pores having an average diameter of from about 1 to about 100 nm and the layer has a pore volume of from about 0.1 to about 2 ml./g., and
- (C) a water-based adhesive in contact with the lower surface of the nano-porous layer.
An adhesive label comprising:
- (A) a polymer facestock having an upper surface and a lower surface,
- (B) a nano-porous layer underlying the facestock and having an upper surface and a lower surface, wherein the nano-porous layer comprises a mixture of a binder and nano-sized inorganic particles, and the nano-porous layer contains pores having an average diameter of from about 1 to about 100 nm and the layer has a pore volume of from about 0.1 to about 2 ml./g., and
- (C) a water-based adhesive in contact with the lower surface of the nano-porous layer.
