Abstract

See full text

The purpose of the present invention is to provide a weather-resistant hard coat composition for a metal, the composition being capable of efficiently forming a coating film excelling in weather resistance, scratch resistance, and flexibility. The present invention provides: a weather-resistant hard coat composition for a metal, the composition containing a polyorganosilsesquioxane having a constituent unit represented by Formula (1); a cured product thereof; and a coated metal substrate having a metal substrate and a coating film formed on at least one surface of the metal substrate. The coating film is a layer of a cured product of the weather-resistant hard coat composition for a metal. [In Formula (1), R1 represents a group containing an active energy ray-curable functional group.]
