Abstract
1533401 Colour-reactive paper combinations FELDMUHLE AG 29 Oct 1975 [29 Oct 1974] 44742/75 Heading D2B A colour-reactive paper combination comprises a donor layer containing a colour former and an acceptor sheet of paper which has at least some of its fibres encapsulated by a colour developer film derived from at least one hydrated film-forming colloidal clay. The latter is incorporated in the stock from which the paper is made. Advantages-improvement in the intensity and sharpness of the coloured image, and savings in manufacturing cost of acceptor sheet.
