Abstract:
A polishing cloth comprising;a polishing cloth substrate;a laminated adhesive layer;a film;a pressure-sensitive adhesive layer laminated in this order on one face of the polishing cloth substrate; anda release sheet attached to the pressure-sensitive adhesive layer adhesive layer in a releaseable manner,wherein the pressure-sensitive adhesive layer comprises an adhesive composition containing a polymer, the polymer having a first-order melt transition occurring in a temperature range narrower than 15.degree. C.,wherein the polymer is a side-chain crystallizable polymer, the side-chain crystallizable polymer being comprised in an amount such that the pressure-sensitive adhesive layer becomes substantially untacky to a base plate of a polishing machine at 20.degree. C. or less and substantially tacky to the base plate of the polishing machine at a temperature higher than 20.degree. C.
