PROBLEM TO BE SOLVED: To color simply as an optional color without using any special material. SOLUTION: This method for producing colored pressure-sensitive adhesive tapes is provided by coloring a supporting material 2 supplied from a supporting material-supplying roll 1 with a kiss roll 4, while applying an adhesive composition on a substrate material 8 supplied from a substrate-supplying roll 9 with a coating device 5. Then, by using a substrate material-pasting roll 7, the colored supporting material 2 and the substrate material 8 are pasted in a state of nipping the pressure-sensitive adhesive composition, and the adhesive composition is supplied to a light-irradiating device 6 for curing. Then, the substrate material 8 is peeled off from the adhesive composition after the photo-curing treatment, and the obtained adhesive sheet is wound on a sheet-winding roll 3.
