  • Patent number: 9505721
    Abstract: [Problem] to provide an aromatic imide compound wherein the sensitivity for visible light such as g-line, h-line etc. is increased and solubility is also improved. [Means for solving problem] The aromatic imide compound of the invention is a compound represented by the formula (1) below (in the formula, R1 represents a haloalkyl group having 1 to 7 carbon atoms or a haloaryl group, R2 represents a group containing a substituted or unsubstituted, aliphatic or aromatic group which may have a heteroatom, and adjacent R2s may form an imido group by connecting each other, R3 represent a halogen atom or a hydrocarbon group, m is zero or an integer of 1 or more, n is zero or an integer of 1 or more, and a sum of n and m is 1 to 6). These compounds are obtained by following processes. A halogenated naphtharic anhydride is reacted with an aromatic group-containing hydrocarbon such as ethynylbenzene to prepare a naphthalic anhydride substituted by an aromatic group-containing group.
