Printing paper and method of manufacturing the same

Abstract

Disclosed is a printing paper comprising a back surface thereof applied with a repositionable adhesive, adhered to a coated surface of a PET sheet paper, which can be freely repositioned and printed at high resolution up to 2800 dpi even by ink-jet printers as well as laser printers. Thus, the printing paper is variously utilized for reports, color-printed paper and public information paper. In particular, the printing paper for use in public information paper. In particular, the printing paper for use in public information paper or guide paper can be attached to any surface in a typical office, and separated therefrom, and again attached to other surfaces. A method of manufacturing be printing paper is also provided.

1 . (cancel)  
     
     
         2 . An improved printing paper of the type in which an adhesive that is repositionable is deposited on a back surface of a printing paper and a PET sheet paper is positioned on the adhesive over the back surface of a printing paper, wherein the improvement comprises: 
 a coating agent deposited on a front surface of a printing paper to increase stickiness of ink jetted by an ink-jet printer.    
     
     
         3 . The improved printing paper as defined in  claim 2 , wherein the adhesive comprises 43-47 parts by weight of vinyl acetate-acrylic acid ester copolymer resin, 1.5-2.5 parts by weight of a nonionic surfactant (poly ory ethylene nonyl phenyl ether), 16-20 parts by weight of an inorganic filler (calcium carbonate), 1,000-2,000 ppm of vinyl acetate monomer, 1,000-2,000 ppm of 2-ethyl hexyl acrylate monomer, and 32-36 parts by weight of water.  
     
     
         4 . The improved printing paper as defined in  claim 2 , wherein the coating agent comprises 23-27 parts by weight of silica, 46-50 parts by weight of a polymeric binder, 1 part by weight of an ink sticking agent, 1 part by weight of an ink fixing agent, and 20 parts by weight of water.  
     
     
         5 . A method of manufacturing an improved printing paper, comprising: 
 (A) preparing a coating agent including 23-27 parts by weight of silica, 46-50 parts by weight of a polymeric binder, 1 part by weight of an ink sticking agent, 1 part by weight of an ink fixing agent, and 20 parts by weight of water;    (B) applying 8.4 g of the coating agent onto a front surface of a printing paper, followed by a drying process at 120° C. for about 20 sec;    (C) preparing an adhesive including 43-47 parts by weight of vinyl acetate-acrylic acid ester copolymer resin, 1.5-2.5 parts by weight of a nonionic surfactant (poly ory ethylene nonyl phenyl ether), 16-20 parts by weight of an inorganic filler (calcium carbonate), 1,000-2,000 ppm of vinyl acetate monomer, 1,000-2,000 ppm of 2-ethyl hexyl acrylate monomer, and 32-36 parts by weight of water;    (D) applying 8.4 g of the adhesive onto a back surface of the printing paper;    (E) adhering the back surface of the printing paper applied with the adhesive to a polyethylene terephthalate sheet paper; and    (F) cutting the printing paper adhered to the sheet paper to a predetermined size.
