Abstract: An embossing varnish for micro- or nanostructured surface layers, in particular a UV-NIL embossing varnish containing a UV-curable compound and an aliphatic photoinitiator, an article with a micro- or nanostructured surface layer on a support, wherein the surface layer is the embossed and UV-cured embossing varnish; a method for producing the article with a micro- or nanostructured surface layer, in particular from bio-based compounds; and the use of the article with a micro- or nanostructured surface layer as a microfluidic structure or film with anti-reflection, flow friction reduction or adhesion effect.

Abstract: A method of preparing an article having an embossed micro- or nanostructured surface using an aqueous dispersion of a curable prepolymer, an article obtainable by the method and the use of the article.

Abstract: A method of manufacturing a component having a microfluidic structure, comprising embossing recesses in an embossed lacquer layer, partially curing the embossed lacquer layer, sealing the recesses with a curable bonding lacquer layer, and curing the partially cured embossing lacquer layer and the bonding lacquer layer, as well as a component obtainable by the method and the use of the component.

Abstract: An embossing lacquer containing radical polymerizable compounds (A) to (D) that have an overall aromatic content of at least 20 wt %: compound (A), which is a non-crosslinking compound and has an aromatic content of at least 40 wt %; compound (B), which is a crosslinking compound forming crosslinks via one or more aliphatic chain(s) each having a molecular weight of 200 to 2000 g/mol, wherein the content of the aliphatic chain(s) in compound (B) is at least 40 wt %; optionally compound (C), which is a crosslinking compound and has an aromatic content of at least 30 wt %; and optionally compound (D), which has a urethane group. A decorative article containing the cured embossing lacquer and a method of preparing the decorative article.

Abstract: A compound of formula (I) wherein n is selected from 3 to 8 and R is hydrogen or a C1-C8 alkyl radical, a process for the preparation of the compound and uses of the compound.

Abstract: A method of drawing an optical fiber through a fabric, having opposite first and second sides, comprises the following consecutive steps: advancing the optical fiber by a fiber transport device in a hollow needle to a predetermined extent; pushing the hollow needle, together with the optical fiber, through the fabric from the first side to the second side until a free end of the optical fiber has traversed the fabric to a predetermined extent; withdrawing the needle from the fabric to the first side thereof while maintaining the optical fiber substantially stationary relative to the fabric; gripping the free end of the fiber by a grasping device on the second side; pulling the optical fiber through the fabric until a predetermined pulled-through length of the optical fiber is obtained on the second side; and servering the optical fiber by a cutting device on the first side.
