Abstract: An insulated wire including a conductor (A) and an insulating layer (B) around the conductor (A). The insulating layer (B) contains an aromatic polyetherketone resin (I) and a fluorine-containing copolymer (II) and has a melt viscosity at 60 sec?1 and 390° C. of 0.40 to 0.75 kPa·s. The aromatic polyetherketone resin (I) has a melt viscosity at 60 sec?1 and 390° C. of 0.30 kPa·s or lower. The insulating layer (B) has a thickness of 30 to 300 ?m.

Abstract: A composition for three-dimensional printing which contains an aromatic polyetherketone resin (I) and a fluorine-containing copolymer (II). The composition satisfies a ratio r2/r1 of 1.60 or lower, wherein r1 represents an average dispersed particle size of the fluorine-containing copolymer (II) and r2 represents an average dispersed particle size of the fluorine-containing copolymer (II) after melt flow rate measurement at 380° C. and a load of 5000 g with 5-minute pre-heating in conformity with ASTM D1238. Also disclosed is a three-dimensionally printed article obtained by three-dimensional printing of the composition for three-dimensional printing.

Abstract: A powder composition containing an aromatic polyetherketone resin (I) and a fluorine-containing copolymer (II). The powder composition has a ratio r2/r1 of 1.60 or lower, wherein r1 represents an average dispersed particle size of the fluorine-containing copolymer (II) and r2 represents an average dispersed particle size of the fluorine-containing copolymer (II) after melt flow rate measurement at 380° C. and a load of 5000 g with 5-minute pre-heating in conformity with ASTM D1238.

Abstract: A film containing a resin composition containing an aromatic polyetherketone resin (I) and a fluorine-containing copolymer (II). The fluorine-containing copolymer (II) defines a dispersed phase at an average dispersed particle size of 5 µm or smaller. The aromatic polyetherketone resin (I) has a crystallinity of lower than 6%.
