Definitions

  • the invention relates to a new process for the preparation of paper with a variety of different pearlescent effect finishes and to the composition used for obtaining such finishes.
  • a further object of the invention is the size press composition used in this process having a viscosity of 1800 cPs ⁇ 50 cPs and comprising a polymeric binder, additives with dispersant, antistatic and lubricant effects, antifoaming agent, a synthetic thickener and a pearlescent pigment.
  • the pearlescent pigment can be any pigment known to give such an effect which is normally provoked by a mica component.
  • pigments sold by the company Merck in Darmstadt, Germany under the name IR1ODIN ® or by the company Maerl International in Haarlem, Holland under the name MAGNAPEARL ® are very suitable.
  • the synthetic thickener can be any thickener used in size process compositions. Examples are the products Printofix Thickener NCN from Clariant or LYOPRINT ® TCF of Ciba Specialty Chemicals.
  • the polymeric binder is of the type having a film forming temperature at around 7 degrees C.
  • An example is the product APPRETAN ® DM2 of the company Perstorp- Clariant which is a copolymer of vinylacetate and dibutylmaleate, stabilized with polyvinylalcohol.
  • composition as above defined can be used in the common size press of a paper machine and/or in a common on-line coating machine as i.e. a blade, air knife or rod coating.
  • the rollers For the application of the composition in a size press of a paper machine according to the invention, the rollers have to be kept as clean as possible in order to get a good runability and it was observed that the drying rollers after the size press should be coated with a fluorinated hydrocarbon resin (TEFLON ® ) in order to avoid adhesion.
  • TEFLON ® fluorinated hydrocarbon resin
  • An important feature of the process according to the invention is the observation of humidity conditions during application of the size press paste and it is advantageous to use a water mist distributor that gives a very fine water mist over the size press rollers.
  • the moisture content in the size-press should be preferably around 100%.
  • the composition can be applied to the paper on one or both sides. If the composition is applied on both side the coatweight need not be the same on both sides.
  • a preferred coatweight for the application of the composition according to the invention is 35 - 40 gm "2 .
  • the pearlescent effect can be varied and many different decorative effects can be produced, for example:
  • the size of the pearlescent particles can be changed to give a course or fine appearance.
  • the color of the pearlescent material can be, for example, silver, gold, blue, red or green
  • the color of the base paper can be varied along with the color of the pearlescence to produce an interesting and decorative range of papers, for example a silver pearlescence on a black paper or board, or a red pearlescence on a blue paper.
  • the combinations are almost without limit.
  • Pearlescent pigments can be mixed together to give two, three or more colors of pearlescence mixed together on the surface of the paper, for example, silver and red, or silver, red, green and blue.
  • the paste obtained in example 1 is applied on a freshly produced paper using size press rollers of the usual type which are kept clean by the application of a very fine water mist provided by a water mist distributor (the moisture content is 100%) at a speed of 200-230 m/min and Nip pressure of 40 kp.
  • a very fine water mist provided by a water mist distributor (the moisture content is 100%) at a speed of 200-230 m/min and Nip pressure of 40 kp.
  • the paper sheet covered by the size paste is lead over drying rollers with a coating of fluorinated hydrocarbon resin at a temperature of 70-75°C. Paper with good pearlescent effect is obtained.
  • the paste obtained in example 1 is applied on a freshly produced paper using an online coating machine (blade coater).
  • the paste is applied to the surface with a coatweight of 35-40 g/m "2 .
  • a paper with excellent pearlescent effect is obtained.

Abstract

La présente invention concerne un nouveau procédé de préparation de papier à finition nacrée. Ce processus consiste à utiliser une composition spéciale, à appliquer cette composition (a) dans une presse encolleuse dans des conditions d'humidité dont la teneur est d'au moins 90 %, et à utiliser des rouleaux de séchage avec un revêtement de résine d'hydrocarbure fluoré, et/ou (b) dans une application de coucheuse directe.
