Abstract:
A method for fabricating a scratch-resistant imaging element having optical clarity, the method comprisinga. dispersing a ceramic nanoparticle material in an aqueous solution of a film-forming hydrophilic colloid comprising gelatin, dextran, gum arabic, zein, casein, pectin, collagen derivatives, collodion, agarâ€”agar, arrowroot, albumin, polyvinyl alcohol, polyacrylamide, poly(vinylpyrrolidone) or a mixture thereof to form a coating composition; b. applying the coating composition to a surface of an imaging layer; c. drying the coated surface; and, optionally, d. aging the dried coated surface, whereby an element protective layer having both optical clarity and resistance to scratching formed over the imaging layer.
