A hyper-branched polymer dispersant represented by, for example, formula (I) has high adhesion properties to a current collector substrate and therefore enables the formation of an electrically conductive bonding layer having high carbon nanotube concentration. When a composite current collector for an energy storage device electrode which is equipped with the electrically conductive bonding layer is used, it becomes possible to produce an energy storage device from which an electrical current can be extracted without causing the decrease in a voltage particularly in use applications that require a large electrical current instantaneously, such as electrical automotive applications, and which has a long cycle life. 

Composite current collector for energy storage device electrode, and electrode

This film-forming composition includes, for example, a polymer, crosslinking agent and light-diffusing agent that contain a triazine ring-containing repeating unit structure such as that represented formula (17), and is able to provide cured films with good light diffusing properties. Furthermore, this film-forming composition, which includes the same polymer, crosslinking agent and fine inorganic particles having a cross-linkable functional group, is able to provide cured films with good high temperature and high humidity resistance.
