Definitions

  • the present invention relates to a coating composition comprising polyurethane microbeads and to the paper coated on at least one face with said coating composition, advantageously on both its faces.
  • Papers of various types or with various compositions can be coated so as to enhance the quality of their surface.
  • a coating composition used conventionally for this purpose is a dispersion comprising pigments, which can be organic or inorganic pigments.
  • the coating composition can also comprise other additives.
  • Paper intended for printing such as paper for books, magazines, brochures or annual reports, or paper intended for packaging is often manufactured by coating a base paper using one or more coating units, sometimes followed by calendering.
  • the final product should generally have surface characteristics improved for the use which is made of it.
  • the Applicant Company thus proposed to provide a characteristic which evokes the destination, namely the skin, that is to say the feel or the softness of the skin.
  • the desired feel could be obtained by applying, to the surface of the sheet, a layer which comprised expandable thermoplastic microspheres.
  • This patent was targeted, inter alia, at solving the problems of machinability of these sheets during printing, in particular the problems of separation of sheets in stacks because of the antislip properties of the added microspheres.
  • coated thin paper often raises serious problems during printing or during converting operations, the commonest being in the context of offset printing: chalking and setting-off.
  • Chalking corresponds to the detachment of the coating in the form of a dry powder during printing, which phenomenon can become more marked with successive passages of the sheet in printing or converting machines.
  • This phenomenon results from poor binder/pigment metering, the pigment being in an excessively high percentage with respect to the binder.
  • Setting-off corresponds to the transfer of print from one sheet to the other, in particular during stacking.
  • the paper can participate in this phenomenon due to the fact that a paper unsuited to the ink can have a poor ability to accept the ink and to the fact that a paper having an uneven surface condition requires too much ink for correct printing.
  • the Applicant Company has endeavored to provide a paper having a silky feel, which are coated preferably on these two faces and which does not exhibit the problems of printability and of machinability stated above.
  • a first aim of the invention is therefore to provide a coating composition for coated papers intended to be printed in offset, characterized in that the pigments used in the coating are polyurethane microbeads having a mean size of less than 10 micrometers and advantageously of approximately 7 micrometers.
  • the binder used in the coating is an aqueous emulsion of polyurethane and preferably a soft polyurethane having a degree of elongation of greater than or equal to 500%.
  • the invention is characterized in that the level of binder with respect to the pigments is greater than or equal to 40% by dry weight and preferably greater than or equal to 200%.
  • Another aim of the invention is to provide a coated paper having a silky feel, comprising at least one face coated with a coating composition as defined above and advantageously these two faces.
  • Said paper is characterized in that it can be printed in offset with low, indeed even nonexistent, setting-off and chalking.
  • the paper is based on cellulose fibers and has a grammage of between 70 and 500 g/m 2 , preferably between 100 and 300 g/m 2 .
  • the paper is transparent or translucent.
  • the paper constitutes a tracing paper.
  • tracing paper is understood to mean a paper as defined by the international standard ISO 4046-1978 in part 6.94.
  • the invention is characterized in that said paper is a tracing paper, obtained in particular by hard beating of the cellulose fibers of which it is composed.
  • the invention is characterized in that the weight of said layer on at least one of the faces is between 2 and 10 g/m 2 on a dry basis, preferably between 3 and 6 g/m 2 .
  • Said paper is also characterized by a coefficient of dynamic friction between its coated recto face and its other verso face, also coated, of less than or equal to 1.0, which measurement is carried out according to the standard NF-Q-03-082 with a block weighing 200 g.
  • the coefficient of dynamic friction reflects the ability of the sheet to stick at the start of a displacement; the higher it is, the greater the difficulty in initiating a movement of a sheet in a stack.
  • a composition comprising polyurethane microbeads of different sizes, as mentioned in table 1, is applied, using an air blade coater, to a sheet of base paper having a grammage of 100 g/m 2 , more specifically the reference Conqueror CX 22 sold by the Applicant Company, in a proportion of 5 g/m 2 approximately per face.
  • composition comprising polyurethane microbeads is prepared in an aqueous medium and comprises, as dry weight:
  • a composition comprising polyurethane microbeads with a mean size of approximately 7 micrometers is applied, using an air blade coater, to a sheet of base paper having a grammage of 100 g/m 2 , more specifically the reference Conqueror CX 22 sold by the Applicant Company, in a proportion of 5 g/m 2 on a dry basis approximately per face, the level of binder being varied with respect to the weight of pigment as mentioned in table 2.
  • composition comprising polyurethane microbeads is prepared in an aqueous medium and comprises, as dry weight:
  • the feel of the face comprising the coating of polyurethane microbeads is assessed by hand.
  • the response of the virgin paper to the chalking test is determined so as to demonstrate the propensity of the coating to disintegrate when passing through a machine.
  • the chalking test is carried out in the following way:
  • the response of the printed paper to the setting-off test is determined, so as to demonstrate the propensity of the paper to result in setting-off during machine stacking.
  • the setting-off test is carried out in the following way:
  • FIGS. 1 and 2 A scanning electron microscope view of a paper exhibiting, from the viewpoint of the Applicant Company, a silky feel has been represented in FIGS. 1 and 2 .
  • This paper was obtained by depositing, on a Conqueror CX 22 base paper having a grammage of 100 g/m 2 , the following coating composition on these two faces:
  • the paper obtained was subsequently calendered.
  • the photographs respectively represent a top view, magnified 200 times, and a cutaway view, magnified 2 000 times.
  • the paper obtained really exhibits a silky feel on these two faces.
