The compounds according to the invention are Si-modified imidyl-phthalic acid derivatives of the formula <IMAGE> (I) and the corresponding cyclized imide derivatives; in the formula, A is a radical which completes to a substituted or unsubstituted imidyl group, R is a divalent organic radical, R1 and R2 are each hydrogen or a monovalent organic radical and Q, Q1 and Q2 are each a monovalent organic radical. A typical example is 3-dimethylmaleimidyl-phthalic acid N-(di-n-propoxymethylsilyl)propylimide, which is obtained by reacting 3-dimethylmaleimidyl-phthalic acid N-allylimide and di-n-propoxymethylsilane in solution, followed by cyclization. The products are used as adhesion promoters, for example between inorganic solids and organic resins.
