<p>No carbon required paper obtained by using synthetic polymer membrane microcapsules as leuco dye solution-retaining microcapsules and using an inorganic solid acid as a color developer can be smoothly used in letter printers without damaging a light-sensitive plate or a master, without giving smell or smoke upon thermal fixing, and without rupture of the microcapsules even in a wet developement process. </p> |
