1. A coated abrasive having at least one layer of adhesive comprising the cured product of liquids containing chemical unsaturation and capable of rapid, spontaneous polymerization initiated by actinic radiation, said cured adhesive being sufficiently deformable at a first temperature of not more than 130°

  • C. to be shaped, along with the backing on which it is coated, into a predetermined curvature by the application of tensile forces less than those required to break the coated abrasive, said cured adhesive further being sufficiently rigid at a second temperature not less than 25°

    C. so as to cause said coated abrasive to retain at said second temperature, in the absence of mechanical forces other than those induced by natural gravity, the curvature imparted to said coated abrasive at said first temperature and maintained during cooling from said first temperature to said second temperature.
