A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.

An object of the present disclosure is to provide an absorbent article without a sticky feel on the top sheet and with a smooth top sheet, even after highly viscous menstrual blood has been absorbed. The absorbent article of the present disclosure is as follows. An absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet and an absorbent body between the liquid-permeable top sheet and liquid-impermeable back sheet, wherein the liquid-permeable top sheet comprises a blood modifying agent with an IOB of 0.00-0.60, a melting point of no higher than 45°C, a water solubility of 0.00-0.05 g in 100 g of water at 25°C, and a weight-average molecular weight of no greater than 1,000.

The present invention relates to a coating composition for an in-vivo implantable prosthesis including a photoinitiator, a crosslinking agent, and a phosphorylcholine (PC) monomer having an acrylate group, a method of coating an in-vivo implantable prosthesis using the coating composition, and a cosmetic prosthesis coated with the crosslinked polyphosphorylcholine. An in-vivo implantable prosthesis coated with crosslinked polyphosphorylcholine may be manufactured by a simple method of applying a coating composition including a photoinitiator, a crosslinking agent, and a phosphorylcholine (PC) monomer having an acrylate group according to the present invention, and then irradiating UV rays. The crosslinked polyphosphorylcholine coating may provide hydrophilicity for the surface and may also remarkably reduce adsorption of proteins and fibroblasts, which may cause side effects such as capsular contracture. Further, the coating has strong enough not to peel off even under stimulation, and therefore, it is maintained under vigorous activity after implantation, thereby being usefully applied to the manufacture of an in-vivo implantable prosthesis with reduced side effects, such as breast prosthesis for cosmetic surgery.
