A process for producing an unsaturated dicarboxylic acid imide compound of formula (I): <IMAGE> (I) wherein D represents a divalent organic group having at least one carbon/carbon double bond; R1 represents an n-valent organic group having at least one carbon atom; and n is an integer of 1 or above, which comprises reacting an unsaturated amide acid compound of formula (II): <IMAGE> (II) wherein D, R1, and n are as defined above, with an orthoester of formula (III): R2-C[-OR3]3 (III) wherein R2 and R3, which may be the same or different, each represents a monovalent organic group having at least one carbon atom, to form an unsaturated dicarboxylic acid amide acid ester compound of formula (IV): <IMAGE> (IV) wherein D, R1, R3, and n are as defined above, and then imidating the compound of formula (IV).
