Abstract
A silver multilayered film comprises at least one intermediate layer comprising a polymeric resin; a colorant composition and a flake composition, wherein the normal to the individual flakes are oriented at an average angle of about 0 to about 75 degrees with a normal to the multilayered film, and wherein the intermediate layer is located between a first layer and an second layer and further wherein the multilayered film has a lightness greater than or equal to about 60 and a change in lightness as a function of viewing angle of greater than or equal to about 40. A multilayered film comprises an intermediate layer disposed on and in intimate contact with a surface of a first layer and a second layer disposed on and intimate contact with a surface of the intermediate layer opposite the first layer, wherein the intermediate layer comprises a polymeric resin; a colorant composition and a flake composition, wherein the normal to the individual flakes are oriented at an average angle of about 0 to about 75 degrees with a normal to the multilayered film, and further wherein the multilayered film has a lightness greater than or equal to about 60 and a change of lightness as a function of …
