1. A coating composition comprising:
(a) a film-forming resin; (b) colored and/or opaque infrared reflective pigment particles; (c) infrared transparent pigment particle; and (d) a tri-block copolymer pigment dispersant; wherein the colored and/or opaque infrared reflective pigment and the infrared transparent pigment are separate and different components and are separately dispersed in the coating composition and wherein the coating composition, when formed into a cured coating, exhibits:
(1) a total solar reflectance of at least 15% as measured in accordance with ASTM E 903-96; and(2) an angle dependent color change of no more than 5 ΔE units at a viewing angle from 110° to −15° when compared to the color of a control coating not containing the colored and/or opaque infrared reflective pigment particles (b). |
