UV PROTECTION PATCH WITH WAVELENGTH CONVERSION FUNCTION

WIPO Patent Application WO/2024/080591

A1

The present invention relates to a UV protection patch with a wavelength conversion function and, more particularly, to a UV protection patch with a wavelength conversion function and capable of effectively blocking ultraviolet rays that may cause skin damage and changing the wavelength by using a phosphor material to promote the skin metabolism and thus to improve the skin. The present invention provides a UV protection patch with a wavelength conversion function, the UV protection patch comprising: a color conversion layer including a water-dispersible polyurethane resin and a red illuminant consisting of a phosphor material which, during relaxation following excitation occurred due to the absorption of light of a first wavelength from natural light or artificial light, emits light of a second wavelength to the human skin; a UV protection layer including a silicone ink resin and an inorganic sunscreen agent; a color imparting layer including a resin composition for coloring; a silicone layer including a soft silicone having a hardness of 5-10°; and a release film layer which removably contacts, via an adhesive means, the adhesion surface of the silicone layer and protects the adhesion surface that is to be attached to the skin.
