The present invention refers to a decorated panel composed as follows: a substrate; a decorative layer applied to at least part of the substrate; a photo-crosslinkable formulation applied directly or indirectly on a part of the substrate and/or on the decorative layer, that is, with the interposition of further layers of intermediate material on at least a part of the substrate and in one or more layers, containing at least one photo-crosslinkable resin; at least one thermoplastic resin; at least one polymerization initiator including but not limited to UV photoinitiators, organic peroxides, Electron Beam.

A coating apparatus for continuously forming a coating layer on each surface of a substrate film includes a water tank located on a movement path of the substrate film, a water tank partition vertically located in the water tank, the water tank partition being configured to partition an inner space of the water tank into two zones, including a first water tank portion and a second water tank portion, a roller unit configured to continuously transfer the substrate film, and a heating unit located outside the water tank. The water tank partition is located spaced apart from an inner bottom surface of the water tank by a predetermined distance.

The present application discloses a coated microneedle with a multilayer structure, including a base, a needle tip on the base, and a functional coating. The functional coating includes a content including a water-soluble polymer material and an active ingredient, and a sustained-release layer wrapping the content. The sustained-release layer covers the needle tip. The coated microneedle can prevent a drug-containing matrix from being quickly dissolved and dispersed, prevent the active ingredient from exuding along with tissues at an action site, and increase the drug intake. The present application further discloses a method for preparing the coated microneedle and a microneedle patch including the coated microneedle.
