BACKGROUND OF THE INVENTION The field of processes for the preparation of polymer compositions is technologically important to several industries, business organizations, and/or individuals. Currently, in hot climates, heat and heat removal remain a major challenge. Light between 400 to (<) 700 nm, preferably 400 to 699 nm, is useful for both animals and plants, however, near-infrared (NIR) light from 700 to 2500 nm from the sun is the main contributor to solar thermal load. Therefore, the elimination of the NIR region whilst maintaining a high photosynthetically active radiation (PAR) is beneficial. Therefore, there is a need for improved (multiple) NIR absorbing materials that may overcome one or more of the above-mentioned problems and/or limitations.
