METHOD OF PREPARATION OF INKS |
摘要 |
<p>A process of producing a non-conductive ink formed from colourant particles and a non-conductive carrier liquid where the colourant particles are inherently of a low electrical resistivity. The process includes the steps of applying to the surface of the colourant particles a material with a high electrical resistivity to give the particle a higher surface resistivity and blending the treated colourant particle with the non-conductive carrier to form the non-conductive ink. The insulative material may be selected from polymers, waxes, organic pigments and dye stuffs and the colourant may be carbon black, magnetic iron oxide or metallic powder.</p> |
