Abstract
A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.
