<p>PURPOSE:To enable a pattern to be directly formed from digital signals by using a transparent heat sensitive recording material capable of forming a color image by heating a photomask film. CONSTITUTION:The transparent heat sensitive recording material to be used has a color image formed on the photomask film by heating, and is provided on a transparent support with a transparent heat sensitive layer capable of developing color by heating, and as the color developing material, a combination of an electron donative dye precursor and a color developing agent or a that of diazo compound and a coupler is used. As the electron donative dye precursor, a colorless or pale-colored compound is properly selected from compounds giving electrons and receiving a proton, such as acid, and developing color, and are embodies by derivatives of triarylmethane, diphenylmethane, and xanthene, thus permitting a pattern to be directly formed by using digital signals.</p> |
