Abstract: Article (9,19) comprising a substrate (10, 20) comprising a polymer and having first (11,21) and second (12, 22) opposed major surfaces. The first major surface (11, 21) has first surface regions (13, 23) with first nanoparticles (14a, 14b, 14c, 14d, 24a, 24b, 24c, 24d) partially embedded into the first major surface (11, 21), and one of • (a) second surface regions (15) free of nanoparticles; or • (b) second surface regions (25) with at least second nanoparticles (28) on the first major surface (11, 21) or partially embedded into the first major surface (11, 21). The first surface regions (13, 23) have a first average surface roughness, R a1 , of at least 20 nm, wherein the second surface regions (15, 25) have a second average surface roughness, R a2 , of less than 100 nm, wherein the first average surface roughness, R a1 , is greater than the second average surface roughness, R a2 , and wherein there is an absolute difference between the first and second average surface roughness of at least 10 nm.

Abstract: A flame-retardant composition is described comprising a mixture of a water dispersible organic polymer; and a water dispersible derivative of an unsaturated dicarboxylic acid or anhydride thereof. The water dispersible derivative typically has a solubility in a 0.1 N aqueous solution of NaOH at 25°C of at least 25 g/liter. Also described is a flame-retardant composition comprising the mixture described dispersed in an aqueous carrier and method of making a flame-retardant composition.

Abstract: A method comprises exposing a particle coating disposed on a thermally-softenable film to a modulated source of electromagnetic radiation. The particle coating comprises distinct particles that are not covalently bonded to each other, and are not retained in a binder material other than the thermally- softenable film. Articles made by the method are 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.
