    Abstract: PROBLEM TO BE SOLVED: To keep neutrality in taste and allow both of cleaning and washing processes to be repeated by making tableware using a composition formed out of highly func tional thermoplastic resin and irradiating a high energy radiation thereto. SOLUTION: Highly functional thermoplastic resin to be used, or polyarylene ether has a repetition unit I, and is expressed as shown in the formula, where (t) and (q) have a value between 0 and 3, and T, Q and Z are independent of one another. The amount of highly functional thermoplastic resin A contained in a composition is advantageously between 1 and 100wt.%, preferably between 10 and 90wt.% and particularly between 30 and 70wt.%. Also, the residue of the composition contains a thermosetting polymer B existing by volume advantageously between 0 and 99wt.%, preferably between 5 and 80wt.% and particularly between 10 and 60wt.%, and at the same time, other additives and a processing assistant C existing by a volume advantageously between 0 and 70wt.%, preferably between 5 and 60wt.% and particularly between 10 and 40wt.%. A laser to be used in this case is a CO2 laser (wavelength: 10.6μm) having a frequency multiplier (wavelength: 532, 355 and 256nm), preferably an excimer laser.
