摘要：
A process for producing an unsaturated dicarboxylic acid imide compound of formula (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):
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):
wherein D, R¹, R³, and n are as defined above, and then imidating the compound of formula (IV).
