| abstract |
The invention relates to a process for coating a substrate with a nitrogen-free compound corresponding to formula (I) and/or a hydrolysis product or condensation productwhereini represents the number 1, 2 or 3,j represents an integer from 1 to 10,k represents the number 0, 1 or 2,k+i is <=3, andR1 represents OH, OR, SH, SR, OOC-R,R represents C1-C10-alkyl or C6-C12-aryl,R2 is an unsubstituted, singly substituted, or doubly substituted methylene group,R3 is a substituted or unsubstituted C1-C10-alkyl or C6-C12-aryl group,R4 represents a C1-C10-alkyl or C6-C12-aryl group, andwherein if j represents from 2 to 10 the methylene groups in the chain may optionally be interrupted once or several times by hetero atoms. |
