Abstract

Binders comprise PA0 A) an aminotriazine derivative in which the primary amino groups of the triazine are methylolated on average with at least one mole of formaldehyde per mole of primary amino groups, and these methylol groups are etherified on average with at least 0.5 mol of primary alcohol per mole of methylol group and the primary alcohols are a mixture containing PA1 a) 0.5-99.5 mol % of a C.sub.1 -C.sub.4 -alkanol and PA1 b) 99.5-0.5 mol % of an alcohol of the formula EQU R.sup.1 --O--R.sup.2 --O!.sub.n --R.sup.3 --OH I, PA2 in which R.sup.1 is C.sub.1 -C.sub.24 -alkyl or C.sub.6 -C.sub.12 -aryl which may be unsubstituted or substituted by from one to three C.sub.1 -C.sub.8 -alkyl groups, and R.sup.2 and R.sup.3 independently of one another are C.sub.2 -C.sub.8 -alkylene and n is an integer from 1 to 100, or of a mixture of higher-boiling alcohols having a boiling point of above 120.degree. C. at 1 bar which contains at least 10 mol %, based on the higher-boiling alcohols, of alcohols of the formula I, and PA0 B) a radical polymer, polycondensation product or polyadduct which is crosslinkable with the aminotriazine derivative.
