    Abstract: A porous coated abrasive article comprises a porous backing having opposed first and second major surfaces, and a porous abrasive layer disposed on the first major surface. The porous backing comprises a porous oriented thermoplastic film. The porous backing has a land portion and openings extending between the first and second major surfaces. Each opening has a respective area at the first surface, wherein the openings have a number density of 5 to 4600 openings per square inch, and wherein the total area of the openings is from 1 to 90 area percent, based on the combined total areas of the land portion and the openings. The porous abrasive layer is disposed on the first major surface of the porous backing. The porous abrasive layer comprises abrasive particles retained in a binder and has an abrading surface opposite the porous backing, and the second major surface of the porous backing and the abrading surface are in fluid communication through at least some of the openings. A method of making the porous coated abrasive article using flame perforation is also disclosed.

    Abstract: A method comprises exposing a particle coating disposed on a nonwoven fiber web comprising thermally-softenable fibers to pulsed electromagnetic radiation having at least one wavelength in the range of 200 nm to 1000 nm. The particle coating comprises distinct particles that are not chemically bonded to each other, and are not retained in a binder material other than the thermally-softenable fibers. Also disclosed are nonwoven articles comprising a thermally-softenable nonwoven fiber web having a particle coating disposed thereon. The particle coating comprises distinct particles that are not chemically bonded to each other and are not retained in a binder material other than the thermally-softenable nonwoven fiber web. The particle coating is at least 60 percent retained after a one minute immersion in isopropanol at 22° C.

    Abstract: An article and a method of making thereof. The article includes a polymeric film having a first major surface and a second major surface; a first plurality of domains of a first inkjet printing ink comprising a first low adhesion backsize coating composition deposited on the first major surface of the polymeric film; and a second plurality of domains of a second inkjet printing ink comprising a second low adhesion backsize coating composition deposited on the first major surface of the polymeric film; wherein the first and second low adhesion backsize coating composition has a viscosity between 1 to 30 cp at a printing temperature between 20 to 70 degrees Celsius; and wherein at least some of the first plurality of domains overlaps some of the second plurality of domains.
