DARK ACRYLIC PRESSURE-SENSITIVE ADHESIVE TAPE |
摘要 |
A pressure-sensitive adhesive tape can be produced by photopolymerization and yet its pressure-sensitive adhesive layer can have a dark appearance when it contains a pigment or dye plus finely divided hydrophobic silica. As compared to a tape which is identical except for omission of the hydrophobic silica, the adhesive layer of the tape is substantially darker and usually of substantially more intense color. Furthermore, the tape exhibits better adhesive properties than do otherwise identical tapes containing no silica. The pressure-sensitive adhesive preferably is an acrylic pressure-sensitive adhesive and may be filled with glass microbubbles which afford a foamlike appearance and character.
