ABSTRACT:
A composition comprising, by weight, the total being 100%:5 to 40% of an amorphous polyamide (B) which results from the condensation of at least one aromatic diacid and with at least one diamine said diamine being optionally cycloaliphatic, and, optionally with at least one monomer chosen from:α,ω-aminocarboxylic acids,aliphatic diacids,aliphatic diamines,0 to 40% of a supple polyamide (C) chosen from copolymers containing polyamide blocks, polyether blocks and copolyamides,0 to 20% of a compatibilizer (D) for (A) and (B),(C)+(D) is between 2% and 50%,with the condition that (B)+(C)+(D) is not less than 30%, and the difference to 100% is made up with a semi-crystalline polyamide (A). This composition can be molded into transparent sheets treated by a sublimation printing process at relatively low temperatures.
