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), A.sub.1-x-y-zB*.sub.yB.sub.2SiO.sub.4:Ln.sup.1.sub.x,Ln.sup.2.sub.z,, 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; Ln.sup.1 is selected from praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln.sup.2 is optionally selected from gadolinium (Gd).

The present disclosure describes tunable methods of treating cellulosic materials with a composition that provides increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

A coated, highly transparent film based on cellulose triacetate, is proposed that includes a) a support film acting as support layer and a cellulose triacetate or a mixture of cellulose esters and cellulose triacetate as main component, the cellulose triacetate or mixture being defined by a haze value of <0.5%, measured on the cellulose triacetate or mixture drawn out to a film after having been dissolved in dichloromethane or acetone, and b) a multi-functional coating applied in a coating solution to one or both sides of the support film. A dissolver medium can also be used as an enclosure medium. The highly transparent films of the invention can be used as window film, sunglasses film, laminating film, furniture foil, enclosing film, slide film for microscopy, cover slip replacement film and/or protective film, adhesive to glass, wood, metal, ceramic, cellulose derivative films or plastics following incipient dissolution or heat treatment.
