20080269049 | Color forming compositions with a fluoran leuco dye having a latent developer - Compositions and systems for production of color images with a fluoran leuco dye having a latent developer are disclosed and described. A color forming composition or composite can include a polymer matrix, a thermally modifiable fluoran leuco dye having a latent developer attached thereto, and a radiation absorber. The thermally modifiable fluoran leuco dye can be developable upon the color forming composition being contacted with electromagnetic radiation which causes the radiation absorber to become energized, so that the energized radiation absorber causes the latent developer to undergo rearrangement to produce an intermediate dye form having a phenolic substituent. The intermediate dye can then undergo an acid catalyzed ring opening to produce a colored dye form. | 10-30-2008 |
20110003687 | Development Of A Thermal Paper Produced On A Very Smooth Paper - A thermal paper is described for the formation of images in thermal printing equipment and their manufacturing process, using high smoothness paper as a base or substrate. The thermal paper object of this invention is more economical and has a fully-acceptable performance. The high smoothness non-coated base paper has a greater high smoothness superficial finish than uncoated paper, and this development had not previously been used industrially for this purpose, since on trying to use the state of art of the process coupled with uncoated paper characteristics, the result was a low quality product. Hence, until now base papers had to be used with a previous coating the preparation of which increased production costs due to finished product characteristics, such as heavier weight (weight by square meter) and also a higher caliber. | 01-06-2011 |
