Abstract: A hard coat film includes a transparent resin film and a hard coat layer disposed on one surface thereof, the hard coat layer being composed of a cured product of a hard coat composition. The thickness of the hard coat layer 0.15 times or more the thickness of the transparent resin film. The hard coat composition has a negative cure shrinkage ratio. The absolute value of the amount of curl of the hard coat film cut into a 100 mm×100 mm square is 20 mm or less. The hard coat layer may contain a cured product of a polyorganosiloxane compound having an alicyclic epoxy group.

Abstract: A hard coat-equipped polyimide film has a hard coat layer (2) on a principal surface of a transparent polyimide film (1). A hard coat composition for polyimide film contains a siloxane compound having an alicyclic epoxy group. The hard coat composition may contain fine particles. The hard coat-equipped polyimide fin is obtained by coating the hard coat composition on a principal surface of a transparent polyimide film and curing the hard coat composition by applying an active energy ray.

Abstract: While green algae are expected to serve as raw materials of biomass fuels, they are damaged by high-intensity light when subjected to mass-culture outdoors in summer, and biomass productivity is deteriorated as a consequence. In order to overcome such a drawback, the present invention provides a high-intensity light resistant green algae mutant that can be subjected to outdoor culture in summer. Specifically, the present invention relates to such green algae mutant, wherein functions or expression levels of a protein having a response regulatory domain at the N-terminus and a WD40 domain at the C-terminus are lower than those in a wild-type strain, and wherein said green algae mutant grows faster than a wild-type strain when cultured at a light intensity of 1,000, 1,500, or 2,000 ?mol photons m?2 s?1 measured as photosynthetically active radiation (PAR).
