2042364 9103381 PCTABS00003 The self-adhesive dry-transfer images of the invention have, applied on a coated paper substrate (ref No. 5 in Figs. 1-3), either two layers, viz: first one or more inks (ref. No. 3 in Fig. 1) and then an adhesive (ref. No. 2 in Fig. 1), or only one layer, viz: a coloured adhesive or an adhesive ink (ref No. 2 in Figs. 2 and 3). The layer(s) are preferably applied by a silk-screen process to sheets of size 140 x 100 cm, at a speed of at least 400-2,000 or 7,200 sheets per hour, each layer coinciding with the image represented by the ink(s). The adhesive is covered by a coated protective paper sheet (ref. No. 1 in Figs. 1 and 2) which adheres easily to the adhesive without the need for other means, but which can be detached again completely from the layered structure (ref. Nos. 2-5 in Figs. 1 and 2) by pulling (ref. No. 7 in Figs. 1 and 2), without pulling the layered structure from the substrate paper (5). In Fig. 3, the back of the substrate paper is also coated for additional protection. The self-adhesive dry-transfer images can be applied to, for instance, a shopwindow (ref. No. 6 in Figs. 1-3) or some other support material, which may have a textile or rounded surface, by pulling off the protective paper sheet (ref. Nos. 7 and 1 in Figs 1 and 2) covering the adhesive, placing the dry-transfer image against the support material, rubbing with light pressure (ref. Nos. 8 in Figs. 1-3) and finally pulling off the sheet of substrate paper (ref. Nos. 9 and 5). The self-adhesive dry-transfer images can normally be removed again easily and without trace from a smooth pane of glass by scraping off with a scraper blade. Any adhesive remaining can be wiped off with water.
