This invention relates to a novel polyimide silicone having an alcoholic hydroxyl group and a process for the preparation thereof. The polyimide of the invention having a primary alcoholic hydroxyl group is represented by the following general formula (1), ##STR00001## wherein X represents a tetravalent organic group, Y represents a divalent group having at least one monovalent group selected from the group consisting of a phenolic hydroxyl group and a carboxyl group, with at least one being a divalent organic group having an alcoholic hydroxyl group, Z represents a divalent organic group, W represents a divalent organic group having an organosiloxane structure, k is a positive number, and each of m and n is equal to 0 (zero) or a positive number, with 0.1.ltoreq.k/(k+m+n).ltoreq.1, 0.ltoreq.m/(k+m+n).ltoreq.0.8, 0.ltoreq.n/(k+m+n).ltoreq.0.8.
