PURPOSE:To enable polishing work with a polishing tape even if it contains polishing substance having high Mohs' hardness without evidence of scratch on the grinding face of the tape by mixing resin, having a polarity radical in the side chain of the chemical formula thereof, with binding agent. CONSTITUTION:Binding agent contains resin having, in the side chain, at least one polarity radical selected from a group consisting of a standard chemical formula. In this formula, the alkyl radical is preferably a saturated fatty acid group hydrocarbon residual radical having a straight chain or a branch chain including 23 or less carbon atoms. M1 and M2 may be either identical or different. Since the resin having such polarity radicals in the side chain has the superior dispersive power, polishing agent can be dispersed sufficiently inside the coating of a polishing means. The surface of a substance to be polished can therefore be polished precisely without any regular and rough part, and additionally, a trace of scratch on the polished surface can be prevented. Polishing agent having high Mohs' hardness compared to a conventional agent and having high polishing efficiency can be mixed in the agent, hence reducing polishing duration. |
