The invention relates to Si-modified phthalic acid derivatives (acids, esters and anhydrides) of the formula I ##STR1## in which R.sub.1 and R.sub.2 independently of one another are --OH, alkoxy with 1-12 C atoms or phenoxy or R.sub.1 and R.sub.2 together are the --O-- group, X is a ##STR2## R.sub.3 is alkyl with 2-7 C atoms, cycloalkyl with 5-7 C atoms, benzyl or ##STR3## Q is methyl, phenyl or --OQ.sub.3 and Q.sub.1, Q.sub.2 and Q.sub.3 independently of one another are alkyl with 1-6 C atoms or phenyl. The products of the invention are prepared by reacting the corresponding allylamino-phthalic anhydrides or allylamino-phthalic acid esters with compounds of the formula III ##STR4## 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.
本发明涉及公式I的硅改性邻苯二甲酸衍生物(酸,酯和酐):
其中R.sub.1和R.sub.2独立地为--OH,具有1-12个碳原子的烷氧基或苯氧基,或R.sub.1和R.sub.2一起为--O--基团,X为##STR2## R.sub.3为具有2-7个碳原子的烷基,具有5-7个碳原子的环烷基,苄基或##STR3## Q为甲基,苯基或--OQ.sub.3,Q.sub.1,Q.sub.2和Q.sub.3独立地为具有1-6个碳原子的烷基或苯基。本发明的产品通过将相应的烯丙基氨基邻苯二甲酸酐或烯丙基氨基邻苯二甲酸酯与公式III的化合物反应制备而成:##STR4## 它们被用作粘附促进剂,例如在无机固体和有机树脂之间。它们也可以用于制备其他硅改性粘附促进剂,并作为环氧树脂的固化剂。
