20100227760 | REIMAGEABLE AND REUSABLE MEDIUM AND METHOD OF PRODUCING AND USING THE REIMAGEABLE AND REUSABLE MEDIUM - The present disclosure provides a reusable and reimageable medium including a substrate coated with a photochromic polymer. The photochromic polymer has a glass transition temperature ranging from 30° C. to 150° C., such as from about 30° C. to about 100° C., and the coated substrate converts to a colored state when both UV light and temperatures ranging from 30° C. up to 100° C. are applied to the coated substrate. The present disclosure also provides a method for producing and using the reusable and reimageable medium. | 09-09-2010 |
20110212396 | BIO-BASED AMORPHOUS POLYESTER RESINS FOR EMULSION AGGREGATION TONERS - Disclosed are amorphous polyesters that contain only renewable resources designed for emulsion aggregation toner fabrication. The amorphous polyesters may be obtained from the mixture of three different monomers: 1,4:3,6-dianhydro-D-sorbitol (isosorbide), nonanedioic acid (azelaic acid), and butanedioic acid (succinic acid). Different polymer properties may be achieved depending on the ratio of these three monomers. By altering the ratio, polymers of high to low acid value can be obtained, as well as different ranges of glass transition temperatures. | 09-01-2011 |
20110281482 | NOVEL LOWER COST REUSABLE POLYMER BINDER - Exemplary embodiments provide compositions for erasable media and methods of forming polymers for erasable media. The method can include providing a first monomer, the first monomer including one or more alkoxylated bisphenols and adding at least one second monomer and a catalyst to the first monomer to form a mixture at a first temperature, the second monomer selected from the group consisting of an organic diacid, a dialkyl ester of the organic diacid, and combinations thereof. The method can also include melt condensing the mixture by increasing the temperature from the first temperature to a second temperature over a first amount of time to form one or more polymers, wherein the one or more polymers has an acid value in the range of about 0.1 mg-KOH to about 12 mg-KOH. | 11-17-2011 |
