Title: Method for forming monochromatic image
Inventor: MITSUCHIERU SUCHIYUWAATO BAABA
IPC: B41M5/26
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain a high contrast monochromatic image by adding an infrared absorbing substance showing absorption at a predetermined wavelength of laser and imagewise heating a hydrophilic water-soluble infrared absorbing layer and a coloring matter barrier layer. SOLUTION: A coloring matter ablative recording element is irradiated with laser to ablate the hydrophilic water-soluble infrared absorbing layer and hydrophobic coloring matter barrier layer thereof to melt and push aside them to expose a lower hydrophilic coloring matter receiving layer. When an ink aq. soln. is brought into contact with the element after irradiation, the coloring matter receiving layer absorbs image forming coloring matter preferentially from the ink aq. soln. in the irradiated part and, therefore, contrast difference is generated between the irradiated region and a non-irradiated region and all remaining infrared absorbing substance is also washed off along with the water-soluble infrared absorbing layer in this dyeing process.
