Disclosed herein is a method for transferring an embossed structure to at least a part of a surface of a coating composition (C2a) using a composite (S1C1) including a substrate (S1) and an at least partially embossed and at least partially cured coating (C1) upon following steps (1), (2-i) and (3-i) or (2-ii) and (3-ii), and also at least step (4) and optionally step (5-i) or (5-ii), where the coating composition (C1a) is a radiation-curable coating composition of defined constitution and the composite (S1C1) is used as embossing mold (e2) of an embossing tool (E2).

Method for transferring an embossed structure to the surface of a coating, and composite employable as embossing mold

The present disclosure relates to a method for transferring an embossed structure to at least a part of a surface of a coating (B2), using a composite (F1B1) composed of a substrate (F1) and of an at least partially embossed and at least partially cured coating (B1), where the coating (B2) and the coating (B1) of the composite (F1B1) have embossed structures which are mirror images of one another. Also described herein is a composite (B2B1F1). Further described herein is a use of this composite for producing an at least partially embossed coating (B2) in the form of a free film or a composite (B2KF2) composed of a substrate (F2), at least one adhesive (K), and the coating (B2).

Method for transferring an embossed structure to the surface of a coating

Described herein is a process for producing a structured article (A1M1) in which a material (M1) including at least one micro- and/or nanostructured surface (SU1) containing a plurality of micro-scale and/or nano-scale surface elements is covered with an at least partially cured coating layer (C2) to provide a composite (M1C2), said composite (M1C2) is attached to an object (A1) and the coating layer (C2) is at least partially peeled off to provide the structured article (A1M1). Also described herein is a composite (M1C2) in which the surface elements of the material (M1) are covered by a protective coating layer (C2).

Process to prepare a structured article using a removable protective layer and structured article obtained by said process

Described herein is a coating composition including a polymer containing hydroxy groups, such as a water soluble polyvinyl alcohol, and further including a tetraalkoxysilane and modified silica nanoparticles having a positively charged surface, where the coating composition shows advantageous properties such as low refractive index, good transparency and low haze.

Optical coating having a low refractive index

The present disclosure relates to a method for transferring an embossed structure to a surface of a coating composition (B2a), which includes the steps (1-i) and (2-i) or (1-ii) and (2-ii) and also the steps (3) and optionally (4), where the steps (1-i) and (2-i) or (1-ii) and (2-ii) are performed using a composite (F1B1) which is employed as an embossing die (p2) of an embossing tool (P2) and which is composed of a substrate (F1) and of an at least partially embossed and at least partially cured coating (B1), and the coating composition (B1a) used for producing (B1) of the composite (F1B1) is a radiation-curable coating composition of defined constitution. Also described herein is a composite (F1B1).

Method for transferring an embossed structure to the surface of a coating means and compound structure usable as an embossing die

Described herein is a photovoltaic module, which includes PV cells capable of converting light incoming from a front side and from a rear side () and a transparent rear side including a rear surface carrying a structured layer (), where the lower surface of the structured layer () is the lower surface of the module, and where the surface of layer () is structured by parallel V-shaped grooves of depth h2 or less than h2, where the lateral faces of the grooves of depth less than h2 form a groove angle beta and adjacent faces of neighbouring grooves form a peak of apex angle alpha, characterized in that h2 is from the range 5 to 200 micrometer, and each pair of neighbouring grooves includes one groove of depth h2 and one groove of depth (h2&#x2212;h1), where h1 ranges from 0.1 h2 to 0.9 h2.
