摘要:
It is an object of the present invention to provide a laser-welded article that workpieces prepared simply can be easily unified by laser in one laser welding process without using complicated processes. Moreover, the laser-welded article has an excellent appearance and sufficient welding strength of the molded workpieces, and does not damage the resin property. The laser-welded article comprises: an integral construction of a single workpiece that at least a part of curled workpiece is overlapped or plural workpieces that at least a part of each workpiece is piled, which is welded by exothermic through irradiating laser, wherein the single laser-transmissible-absorptive molded workpiece or the plural laser-transmissible-absorptive molded workpieces include a thermoplastic resin and a laser-transmissible absorbent to have an absorbance: a ranging from 0.07 to 2.0, and have abilities of absorbing at least partial beam of the laser and transmitting another partial beam of the laser.

The present invention relates to a method for producing an α-form titanylphthalocyanine represented by the formula (1):
which has a peak at a Bragg angle (2θ ± 0.2°) in X-ray diffraction spectrum with CuK α-ray: 7.5°, 10.2°, 12.6°, 13.2°, 15.1°, 16.3°, 17.3°, 18.3°, 22.5°, 24.2°, 25.3° and 28.6°, wherein the method includes steps of: (I) subjecting a crude titanylphthalocyanine having an α-form polymorph to an acid pasting treatment, and then filtering and washing with water to give a water-containing wet cake, and then subjecting the wet cake to drying and crushing to give a low crystalline titanylphthalocyanine; (II) adding a dispersing aid to the low crystalline titanylphthalocyanine and dispersing at room temperature, in DMF, to prepare a polymorph; and (III) filtering, washing, and drying under a reduced pressure. The present invention consists in a provision of a method for conveniently producing the α-form titanylphthalocyanine having a peak at a Bragg angle (2θ ± 0.2°) in X-ray diffraction spectrum with CuK α-ray: 7. 5°, 10. 2°, 12. 6°, 13.2°, 15.1°, 16.3°, 17.3°, 18.3°, 22.5°, 24.2°, 25.3° and 28.6°, wherein a crude titanylphthalocyanine having an α-form polymorph is used as a starting material, as well as a provision of an electrophotographic photoreceptor comprising a charge generating material of the α-form titanylphthalocyanine which has excellent photosensitive characteristics.
