Abstract: The present invention relates to processes for staining biological samples, and in particular to automated processes for staining biological sample with hematoxylin stains. In the processes and systems of the invention, separate hematein and mordant solutions are provided which may be premixed prior to application to a biological sample. This method prevents precipitation common in hematein staining solutions and which fouls automated slide/sample processing equipment.

Abstract: A thermal dye image receiver element has, in order, a cellulosic raw base support, an antistatic subbing layer, and a thermal dye receiving layer. The cellulosic raw base support has an internal electrical resistance (WER) that is at least 1 log ohm/square greater than the surface electrical resistance (SER) of the antistatic subbing layer. This arrangement of antistatic properties overcomes a static problem in the thermal dye image receiver elements by properly balancing the conductivity between the two antistatic locations.

Abstract: Disclosed is an imaging element comprising a bichromophoric molecule comprising a first chromophore that exhibits a first absorption maximum above 700 nm and a second chromophore that exhibits a second absorption maximum different from the first absorption maximum, wherein the absorption of the first and second chromophores are substantially independent of each other, and a process for imaging using such a donor element. Elements of the invention eliminate unwanted absorptions in the final image.
