Abstract
An object of present invention is to provide a diamine and an acid dianhydride having photoreactivity and thermoreactivity and a polyimide composition containing the diamine and the acid dianhydride as monomer components, and specifically to synthesize a diamine and an acid dianhydride having a photoreactive and thermoreactive group containing a double bond or triple bond such as cinnamic acid, chalcone, benzalacetophenone, stilbene, coumarin, pyrone, allyl, propargyl, and acetylene or a derivative skeleton thereof so as to exhibit photoreactivity and thermoreactivity specific to the reactive group, thereby providing a polyimide composition containing the diamine and the acid dianhydride.
