1. , a kind of epsilon-copper phthalocyanine, be characterised in that:

  • in CuK α

    X-ray diffraction intensity distribution plan, the diffracted intensity value of Bragg angle 2 θ

    during as baseline with straight line that the point on the described distribution plan of the point on the described distribution plan of Bragg angle 2 θ

    =5 ° and

    Bragg angle 2 θ

    =12 °

    is connected=6.8 °

    is set at A, maximum diffraction intensity level in the scope of Bragg angle 2 θ

    =9.1 °

    ±

    0.2 °

    is set at B, when the minimum diffracted intensity value in the scope of Bragg angle 2 θ

    =8.6 °

    ±

    0.2 °

    is set at C, satisfy relational expression ;

    -0.05≤

    (A-C)/(A-C+B)≤
