Colored foamlike pressure-sensitive adhesive tape. |
摘要 |
The invention provides a foamlike pressure-sensitive adhesive tape comprising a flexible carrier supporting one or more pressure-sensitive adhesive layers, at least one layer of the pressure-sensitive adhesive having pigment-coated microbubbles dispersed therein having an average diameter from 5 to 200 micrometers, wherein the pigment coating comprises finely divided pigment particles, the average particle size being no greater than 1/100 the average size of the microbubbles. The invention further relates to a method for making coated microbubbles involving rolling the pigment and the microbubbles in a cylindrical container with two or more mixing rods having lengths at least about equal to the interior diameter of the container, and a combined surface area at least about 5% of the interior surface area of the container.
