ABSTRACT:
In a thermoplastic polyester, a compound having at least two ethylenically unsaturated groups and/or oxirane rings in one molecule is coated as a crosslinking agent on the outer surface of the polyester substrate, or a polyester composition containing this crosslinking agent is laminated on the polyester substrate as the inner surface layer, and the crosslinking agent or the crosslinking agent-containing polyester composition is irradiated with ionizing radiant rays or ultraviolet rays. In this processed vessel, the dimension stability and rigidity are highly improved, and deformation under heat and/or pressure can be effectively prevented.
