Abstract: 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 (I), A1-x-y-zB*yB2SiO4:Ln1x,Ln2z,, where x=0.0001-0.05, z=0 or z=0.0001 to 0.3, and y=x+z; A is selected from Mg, Ca, Sr, and Ba; B is selected from Li, Na, K, Rb, and Cs; B* is selected from Li, Na, and K; where B is the same as B* or B is not the same as B*, and B and B* are preferably not the same; Ln1 is selected from praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln2 is optionally selected from gadolinium (Gd).

Abstract: A curable composition for production of coatings having an antimicrobial property, contains at least one film-forming polymer, optionally at least one additive and/or at least one curing agent, and at least one up-conversion phosphor of the general formula (I): A1-x-y-zB*yB2SiO4:Ln1x,Ln2z. In the general formula (I), x=0.0001-0.0500; z=0.0000 or z=0.0001 to 0.3000 with the proviso that: y=x+z; A is selected from Mg, Ca, Sr and Ba; B is selected from Li, Na, K, Rb and Cs; B* is selected from Li, Na and K; and preferably B and B* are not the same. Additionally, Ln1 is selected from praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln2 is gadolinium (Gd). The phosphor has been prepared using at least one halogen-containing flux.

Abstract: 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.
