## Claims

### Claim 1

A thermoplastic molding material containing
A) from 1 to 98.5% by weight of a partly aromatic copolyamide,
B) from 1 to 98.5% by weight of a polymethacrylimide,
C) from 0.5 to 30% by weight of a polycondensate of aliphatic or aromatic polyhydric alcohols with epihalohydrins,
D) from 0 to 60% by weight of fibrous or particulate fillers or mixtures thereof,
E) from 0 to 40% by weight of rubber impact modifiers and
F) from 0 to 40% by weight of conventional additives and processing assistants.

### Claim 2 (depends on 1)

a.sub.1) from 30 to 44 mol % of units which are derived from terephthalic acid,
a.sub.2) from 6 to 25 mol % of units which are derived from isophthalic acid,
a.sub.3) from 43 to 49.5 mol % of units which are derived from hexamethylenediamine and
a.sub.4) from 0.5 to 7 mol % of units which are derived from liphatic cyclic diamines of 6 to 30 carbon atoms,
the molar percentages of the components a.sub.1) to a.sub.4) together giving 100%.

### Claim 3 (depends on 1)
