Abstract (en)
[origin: EP3480028A1] Provided are a friction body capable of reducing paper soiling caused by a strong force and/or repeated rubbing motion, and a writing instrument and writing instrument set provided with that friction body. Provided are a friction body that allows an image having thermochromicity to change color with frictional heat, the friction body containing a styrene-based elastomer, and having compression set at 120°C of 80% or less, and Shore A hardness of 60 to 98, and a writing instrument and writing instrument set provided therewith. The styrene-based elastomer is preferably crosslinked.
