A system for applying a coating composition to a substrate utilizing a high transfer efficiency applicator is provided herein. The system includes a storage device for storing instructions for performing a matching protocol, and one or more data processors configured to execute the instructions to, receive, by one or more data processors, target image data of a target coating, the target image data generated by an electronic imaging device, and apply the target image data to a matching protocol to generate application instructions. The system further includes a high transfer efficiency applicator defining a nozzle orifice. The high transfer efficiency applicator is configured to expel the coating composition through the nozzle orifice to the substrate to form a coating layer. The high transfer efficiency applicator is configured expel the coating composition based on the application instructions.

A visible light-curable chitosan derivative, a hydrogel thereof, and a preparation method therefor are disclosed. The visible light-curable glycol chitosan derivative is curable by light in the visible light range and has a wound healing activity. A hydrogel obtained by cross-linkage of the visible light-curable glycol chitosan derivative using visible light has a wound healing effect per se, and further, a hydrogel obtained by cross-linkage in a combination of one or more growth factors has an excellent wound healing effect. In addition, a glycol chitosan hydrogel that can prevent the denaturation of contained drugs and growth factors due to the cross-linkage by visible light and is optimized for application to a wet dressing dosage form can be prepared.

The present invention relates to a polymer composition, which contains or consists of a matrix of at least one thermoplastic polymer capable of crystallization and, incorporated therein, at least one azine dye and at least one ion liquid. Said polymer composition is characterized in that the crystallization point relative to non-additivated polymer compositions is substantially reduced. The invention further relates to a corresponding additive composition for the crystallization and/or for the lowering of the crystallization point of thermoplastic polymers or polymer compositions capable of crystallization.
