    摘要: 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.

    摘要: The compounds according to the invention have the formulae Ia or Ib ##STR1## in which Y is a divalent organic radical and Z is --NH.sub.2, --NH-alkyl having 1-4 C atoms, --OH, --COOH, --COCl, --O--CO--CH.dbd.CH.sub.2, ##STR2## --COO--CH.dbd.CH.sub.2 or --O--CH.dbd.CH.sub.2. These novel 3- or 4-azidophthalic acid derivatives may be used for the preparation of photo-crosslinkable polymers. Compared to corresponding photosensitive polymers of the prior art, these novel polymers have the advantages that they are even more photosensitive and that they also absorb in the long wavelength UV region (at wavelengths greater than 320 nm).
