La invención se refiere a una composición curable para producir recubrimientos con propiedades antimicrobianas que contiene al menos un polímero formador de película, al menos un fósforo de conversión ascendente, opcionalmente al menos un aditivo, opcionalmente al menos un endurecedor, siendo seleccionado el fósforo del general idealizado fórmula (I)Lu3-ab-nLnb(Mg1-zCaz)aLin(Al1-u-vGauScv)5-a-2n(Si1-d-eZrdHfe)a+2nO12Idonde a = 0 - 1, 1 >= b > 0, d = 0 - 1, e = 0 - 1, n = 0 - 1, z = 0 - 1, u = 0 - 1, v = 0 - 1, con u+v <= 1 y d+e <= 1;Ln = Praseodimio (Pr), Gadolinio (Gd), Erbio (Er), Neodimio (Nd), Itrio (Y),Lu = Lutecio,Li = Litio. (Traducción automática con Google Translate, sin valor legal) A curable composition, for production of coatings with an antimicrobial property, contains at least one film-forming polymer, at least one up-conversion phosphor, optionally at least one additive, and optionally at least one curing agent. The phosphor is selected from the idealized general formula (1), Lu3-a-b-nLnb(Mg1-zCaz)aLin(Al1-u-vGauScv)5-a-2n(Si1-d-eZrdHfe)a+2nO12, where a=0-1, 1≥b>0, d=0-1, e=0-1, n=0-1, z=0-1, u=0-1, v=0-1; with u+v≤1 and d+e≤1; Ln=praseodymium (Pr), gadolinium (Gd), erbium (Er), neodymium (Nd), or yttrium (Y); Lu=lutetium; and Li=lithium.
