COLORED FOAMLIKE PRESSURE-SENSITIVE ADHESIVE TAPE |
摘要 |
The invention relates to a foamlike pressuresensitive 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 coat comprises pigment particle aggregates having an average aggregate size being from about 0.5 microns to about 5 microns. The invention further relates to pigment-coated microbubbles, and 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. |
