Abstract
This invention relates to the construction of backings for coated abrasive products that avoid curling tendencies during adhesive curing and subsequent steps. Curling of the backing is discouraged by the utilization of at least one finishing material carried by said fabric which comprises the product of a reaction between an unsaturated hexafunctional acrylated urethane oligomer component and an unsaturated carboxyfunctional monomer component. These components are caused to react with one another to form cross linking when exposed to actinic or electron beam radiation.
