    Abstract: A tough polymeric mixture comprises the polymerized product of admixture I or II, wherein admixture I comprises 5 to 45 weight percent of a first monomer and a photoinitiator therefor, said first monomer being at least one free-radically polymerizable monomer, and 95 to 55 weight percent of a second monomer and a photoinitiator therefor, said second monomer being at least one set of polyurethane precursors, and admixture II comprises 5 to 45 weight percent of a first monomer and a photoinitiator therefor, said first monomer being at least one set of polyurethane precursors, and 95 to 55 weight percent of a second monomer and a photoinitiator therefor, said second monomer being at least one free-radically polymerizable monomer, said polymeric mixture having been prepared by a process involving two sequential actinic radiations of wavelength ranges centered around μ1 and μ2, respectively, wherein μ1 and μ2 differ from each other by at least 30 nm, and wherein the actinic radiation centered around μ1 does not substantially polymerize the second monomer, and wherein the area under a stress-strain curve as determined by ASTM D638-89 for said polymeric mixture is at least 10 percent greater, preferably 20 percent greater, and more preferably at least 50 percent greater when said precursor monomers are cured by said sequential photoinitiation process compared to when the same mixture is cured by a single photostage cure.

    Abstract: A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for cross-linking the epoxy resin that is cured to provide a cross-linked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated porous cloth material.

    Abstract translation: 涂覆的磨料制品包括背衬，背衬上的第一粘合剂（即，底漆）和第一粘合剂中的多个磨料颗粒。 第一粘合剂前体是含有环氧树脂，聚酯组分，多官能丙烯酸酯组分和用于交联环氧树脂的固化剂的能量可固化的可熔融加工的树脂，其被固化以提供交联的制造涂层。 本发明还涉及生产这种涂覆的磨料制品和表面处理的多孔布材料的方法。
