Abstract:
1. A colored transparent article comprising: a thermoplastic polymer matrix; a plurality of domains; and one or more light absorbing compositions; wherein the measured haze of the article in the absence of the one or more light absorbing compositions is at least 4%; wherein said domains each encompass at least one incompatible filler, dispersed in the thermoplastic polymer matrix, wherein the domains have a range of dimensions in an axial plane of the article, wherein the dimensions of at least some of the domains in the axial plane of the article fall within a range of from about 400 nm to about 700 nm; wherein the one or more light absorbing compositions is present in an effective amount to alter the light absorption of the colored transparent article so that the light absorbed by a single continuous portion of the colored transparent article is such that the total amount of relative light available for reflectance, X, is less than 9.6 in an equation where A where N where the wavelength i ranges from 400 nm to 700 nm; wherein said colored transparent article is of a single layer construction; and wherein the thermoplastic polymer matrix is selected from the group consisting of linear polyesters, branched polyesters, polyamides, polystyrenes, polycarbonates, polyvinylchlorides, polyacrylamides, polyacrylonitriles, polyvinylacetate, polyvinyl methyl ether, ethylene vinyl acetate copolymer, ethylene methyl acrylate copolymer, low molecular weight polyolefins having 2 to 8 carbon atoms, and copolymers, terpolymers, and blends thereof.
