Abstract: A pigment composite particle is provided. The pigment composite particle is a covalently bonded product of a crosslinking structure having silicon-oxygen bonds and a plurality of organic pigment particles. The plurality of organic pigment particles are dispersed in the crosslinking structure. The chemical structure of the organic pigment particle includes C═O and one or more structures selected from the groups defined in the specification. A weather resistant coating composition and a weather resistant structure employing the same are also provided.

Abstract: A pigment composite particle is provided, which includes an organic pigment core, a polyelectrolyte shell wrapped around the organic pigment core, and an oxide shell wrapped around the polyelectrolyte shell. The organic pigment core is water-insoluble. The organic pigment core and the polyelectrolyte shell have a weight ratio of 1:0.25 to 1:1. The oxide shell is formed from tetraalkyl orthosilicate, tetraalkyl orthotitanate, or a combination thereof, and the organic pigment core and the tetraalkyl orthosilicate, tetraalkyl orthotitanate, or the combination thereof have a weight ratio of 1:0.7 to 1:3.
