Abstract The invention relates to Si-modified phthalic acid derivatives (acids, esters and anhydrides) of the formula I (I) Image in which R1 and R2 independently of one another are -OH, alkoxy with 1-12 C atoms or phenoxy or R1 and R2 together are the -O- group, X is a Image or Image group, R3 is alkyl with 2-7 C atoms, cycloalkyl wltb 5-7 C atoms, benzyl or Image Q is methyl, phenyl or -OQ3 and Q1, Q2 and Q3 independently of one another are alkyl with 1-6 C atoms or phenyl. The products of the invention are prepared by re- acting the corresponding allylamino-phthalic anhydrides or allylamino-phthalic acid esters with compounds of the formula III Image (III) They are used as adhesion promoters, for example between inorganic solids and organic resins. They may also be used for the preparation of other Si-modified adhesion promoters, and as curing agents for epoxide resins.
