    摘要： The invention provides an improved method of transparentizing a paper substrate to produce a translucent area or “window” through which information and data are displayed. The method of the invention applies a transparentizing material to a preselected application site of the paper substrate, and exposes the transparentizing material to heat for a predetermined period of time to help facilitate penetration of the transparentizing material into the paper substrate and prevent migration of the transparentizing material from the application site. The rate of penetration of the transparentizing material into the paper substrate reduces the time and increases the efficiency of the transparentizing process. The invention also provides a paper substrate and a one-piece paper assembly in which a translucent area or “window” is formed according to the method of the invention.

    摘要： The invention relates to improvements in security features in paper and in particular to a method of making paper and transparentising selected areas of paper to provide enhanced security features. The invention thus provides a method of making paper comprising the step of depositing fibers (12) onto a support surface (13) to form a porous absorbent sheet (14), applying a transparentising resin to at least portion of said porous sheet and subsequently impregnating the porous sheet with a sizing resin.

    摘要： A transparentized paper is prepared by coating a transparentizing medium on to a paper substrate by a screen coating process. The method may be carried out on a continuous basis, and the medium may comprise an ultra-violet curable resin. Also disclosed is a universal vellum prepared according to the method of the invention, and having a first side which has a smooth texture and may be utilized for electrostatic, pen plotter and xerographic applications, and a second side having a rougher texture which may be utilized for drafting and ink-jet printing applications.
