Zusammenfassung: | The present invention relates to hot-melt adhesive coating solutions which contain
A) from 5 to 80% by weight of a copolyamide built up from units derived from
A1) organic dicarboxylic acids
where R is an aliphatic radical having from 1 to 20 carbon atoms or an aromatic radical having from 5 to 25 carbon atoms,
and
A2) a mixture of diisocyanates comprising
a21) from 20 to 95 mol% of a diisocyanate of the formula
OCN-R -NCO
where R is an aromatic radical having 5 to 25 carbon atoms,
a22) from 5 to 70 mol% of a diisocyanate of the formula
OCN-R -NCO
where R is
or a linear aliphatic radical having 3 to 30 carbon atoms which is substituted by 1 to 3 C1-C4-alkyl groups, and R and R , independently of one another, are each a C1-C4-alkyl group or a hydrogen atom,
a23) from 0 to 20 mol% of a diisocyanate of the formula
OCN-(CH2)y-NCO
where y is an integer in the range from 1 to 20,
and
B) from |
