    • A process for manufacturing an abrasive tape comprising the steps of preparing a coating solution by mixing, as main constituents, abrasive grains, a binder, and a solvent, applying this coating solution on a substrate and drying the coating, and curing the binder, wherein the binder used in preparation of the tape as its essential components either:I. (a) a polymer having repeating units of the formula ##STR1## and having a number average molecular weight of 1,000 to 5,000 (b) a polyester resin containing in its molecule a condensate of an aromatic dicarboxylic acid or an aliphatic dicarboxylic acid or an aromatic dicarboxylic acid and an aliphatic dicarboxylic acid, and an aliphatic diol and having a number average molecular weight of 10,000 to 30,000 terminal OH groups and a glass transition point (Tg) of -20.degree. C. to 40.degree. C., and(c) a polyfunctional isocyanateII. (a) a polymer having repeating units of the formula ##STR2## (b) a polyurethane resin having a number average molecular weight between 5,000 and 20,000 and terminal OH groups, and(c) a polyfunctional isocyanate.(d) the component II (a) to II (b) ratio by weight being in the range 10:90 to 40:60.

    • To provide an abrasive material which is excellent in loading resistance and durability, allows no attachments to attach to an abraded surface even when the end surface of the optical fiber is abraded, and is particularly suited for use in abrading a hard material such as an end surface of an optical fiber connector effectively and smoothly into a predetermined shape. The present invention provides an abrasive material for abrading an end surface of an optical fiber connector into a predetermined shape, the abrasive material having a base material (101) and an abrasive layer (102) disposed on the base material, the abrasive layer having a top layer (105) comprising an abrasive composite containing abrasive grains and a binder and a foot portion (106) comprising a binder in the absence of abrasive particles, the abrasive layer having a three-dimensional structure constructed with a plurality of regularly arranged three-dimensional elements (104) having a predetermined shape. Further, the present invention provides a method for producing an abrasive material having an abrasive layer of a three-dimensional structure, the method comprising the steps of: (1) filling a mold sheet having a plurality of regularly arranged recesses, with an abrasive material coating solution containing abrasive grains, a binder, a solvent, to a predetermined depth; (2) removing the solvent from the abrasive material coating solution in the recesses by evaporation; (3) filling the recesses further with a binder; (4) laminating a base material on the mold sheet to bond the binder to the base material; and (5) hardening the binder.
