1. A layer for an abrasive article, the layer comprising:
a body having a thickness, T, comprising:
a first major surface; and
a second major surface opposite the first major surface;
the body comprising a curable composition comprising:
(a) a polymerizable epoxy-acrylate resin composition comprising from about 15 to about 50 parts by weight of an acrylic copolymer relative to 100 parts of the curable composition and having a complex viscosity at 25° C. and 1 Hz frequency of about 1,000 Pa-s to about 100,000 Pa-s and a complex viscosity at 125° C. and 1 Hz frequency of about 10 Pa-s to about 10,000 Pa-s; and
(b) abrasive particles at least partially embedded in the polymerizable epoxy-acrylate resin composition; and

wherein the body includes a plurality of void spaces free of the curable composition extending into the body from the first major surface and the depth of the plurality of void spaces is at least 10 percent of thickness T.
