PROBLEM TO BE SOLVED: To suppress peeling between a substrate and a colored layer in a composite substrate, in a colored adhesive tape using a composite substrate formed by sandwiching a colored layer with two substrates.SOLUTION: There is provided a colored adhesive tape 1 which comprises: a composite substrate 2 obtained by sequentially laminating a sheet-like first substrate 21, a colored layer 23 containing a colorant and an adhesive and a sheet-like second substrate 21; and an adhesive layer 3 laminated on the first substrate of the composite substrate 2, wherein the Elmendorf tear strength of the second substrate 22 is lower than the Elmendorf tear strength of the first substrate 21 and is in the range of 3 mN or more and 55 mN or less.SELECTED DRAWING: Figure 1 |
