<p>Disclosed is a composite film having photocurability and weather resistance. The composite film contains at least a urethane polymer, and the initial b* value (at an angle of 15°) as measured by a spectrocolorimeter and the b* value after 120 hours in an accelerated weathering test (at an angle of 15°) are both not more than 4.0. The composite film has a nonvolatile component of not less than 96% after 2-hour heating at 130°C.</p>
