Abrégé
Provided are: a novel imide-modified organopolysiloxane in a liquid form having excellent resistance to heat; a method for producing the organopolysiloxane; and a curable composition that contains the organopolysiloxane and that can be cured by irradiation with light without using an initiator. The organopolysiloxane is represented by formula (1). (Wherein: each R 1 represents an unsubstituted or substituted monovalent hydrocarbon group having 1-10 carbon atoms or an organic group having a structure represented by formula (2) or (3), and at least one of the R 1 s is the organic group having a structure represented by formula (2) or (3); a represents an integer of 2 or more; b, c, and d each represent an integer of 0 or more; and 2 ¤ a+b+c+d ¤ 1,000 is satisfied.) (Wherein: R 2 -R 7 each represent a hydrogen atom or an unsubstituted or substituted monovalent hydrocarbon group having 1-10 carbon atoms; R 2 or R 3 may be linked with R 4 or R 5 to form a ring, and R 6 may be linked with R 7 to form a ring; m and n each represent an integer of 0-3; and X and Y each represent an unsubstituted or substituted divalent hydrocarbon group that has 1-10 carbon atoms and that optionally contains an intervening heteroatom. A dashed line represents a bond.)
