20090137389NOVEL COLOR-FORMING COMPOUNDS AND USE THEREOF IN IMAGING MEMBERS AND METHODS - There are described novel rhodamine color-forming compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form. Thermal imaging members containing these color-formers are also described.05-28-2009
20100087316Thermally-Insulating Layers and Direct Thermal Imaging Members Containing Same - Multicolor thermal imaging members are described that comprise color-forming layers that are separated by thermally-insulating layers and can be addressed with a thermal printing head in contact with a surface to form an image. The thermally-insulating layers are designed to be as thin as possible consistent with at least partially independent addressing of the color-forming layers, and are formulated so as not to lead to instabilities either before or after printing or to give rise to dimensional changes of a thermal imaging member when it is subjected to changes in temperature or humidity. Coating compositions for manufacturing such thermally-insulating layers are also provided.04-08-2010
20110098487NOVEL COLOR-FORMING COMPOUNDS AND USE THEREOF IN IMAGING MEMBERS AND METHODS - There are described novel rhodamine color-forming compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form. Thermal imaging members containing these color-formers are also described.04-28-2011
