<p>By having a surface coat formed on a transparent recording sheet, which coat dissolves or swells upon contact with a high-boiling solvent contained in the ink, it is possible to print characters or figures as well on transparent sheets, such as those for an overhead projector, by the means of printing, such as a word processor, which use inks containing high-boiling solvents. In this method of direct recording, the property of characters, figures, or the like to take on a transparent film is the most important factor which governs its commercial feasibility.</p> |
