Solar heat-shielding coating composition and coated structure

The solar heat-shielding paint composition of the present invention contains a solar heat-shielding pigment having a grain size of 50 .mu.m or less in a proportion of from 2 to 60% by weight of the solid content of the composition as a part or all of the pigment. The solar heat-shielding paint-coated structure having an outermost overcoat layer made of the said paint composition on the structure base displays an excellent solar heat-shielding effect and has a long-time durability with no problem of environmental pollution. The overcoat may be colored in any desired color to give a beautiful outward appearance. The coated structure is extremely useful as an outdoor structure, for example, marine structures such as decks or tanks of ships, as well as land structures such as architectures of petroleum tanks, houses, buildings, storehouses or gymnasia, and cars, tank lorries and refrigerator containers.
