ABSTRACT:
In a hot melt ink of the present invention, a paraffin wax and an ethylene-vinyl acetate copolymer are heated and melted, and a carbon black is added therein and is dispersed with its diameter of substantially 1-30 .mu.m. In a dot printed with this hot melt ink, the area of the recorded dot is smaller than the area of the printed dot, and it is possible to print the dot in a high density. Therefore, the hot melt ink of the present invention excels in a color fastness to heat, a color fastness to light, and a color permanence, and a dot image having higher density can be printed.
