ABSTRACT:
An abrasive tape comprises a flexible substrate and an abrasive layer, which is overlaid on the flexible substrate and contains abrasive grains and a binder. The abrasive grains comprise first abrasive grains, which have a mean grain diameter falling within the range of 0.07 .mu.m to 0.40 .mu.m and a Molls hardness falling within the range of 5 to 7, second abrasive grains, which have a mean grain diameter falling within the range of 0.20 .mu.m to 0.60 .mu.m and a Molls hardness not lower than 8.5, and fine diamond grains, which have a mean grain diameter falling within the range of 0.5 .mu.m to 3.0 .mu.m. The proportion of the fine diamond grains is not lower than 4% by weight with respect to the total weight of the first and second abrasive grains. The proportion of the fine diamond grains having grain sizes not larger than 33% of the mean grain diameter is not higher than 6% by volume with respect to the whole volume of the fine diamond grains. Also, the proportion of the fine diamond grains having grain sizes not smaller than 428% of the mean grain diameter is not higher than 5% by volume with respect to the whole volume of the fine diamond grains.
