Definitions

  • the invention relates to methods for producing individual types of printed matter and, in particular, to a method for forming relief images on a basis.
  • Disadvantages of the known methods for the production of relief include a large amount of energy which is required to deform the base material and an absolute impossibility of use in cases where a base material cannot tolerate deformation due to its low strength or if a deformation of the functionality of a product, e.g. Membranes, can interfere.
  • the flat relief image is applied by application in the process for forming relief images on a base, which comprises the execution of a flat relief image on a base and a subsequent treatment of the base and image by means of a composition which contains a relief-forming material at least once executes at least one composition which contains a destabilizer of a liquid dispersion, and the base and image are treated by means of a liquid dispersion whose disperse phase serves as a relief-forming material.
  • an aqueous polymer dispersion as the liquid dispersion. Natural, synthetic and artificial polymers and mixtures thereof are used as polymers in this process.
  • a disperse phase can be both polymers belonging to elastomers and hardened polymers as well as their mixtures. Thanks to this fact, it is possible to give a relief-forming material the broadest spectrum of chemical, physical and mechanical properties confer, whereby the functional and usage properties of the products are determined with relief images.
  • the elastomers used as relief-forming substances ensure such properties of the relief image as elasticity and flexibility.
  • the polymers, which are in a hardened state ensure such properties of the relief image as hardness, smoothness and wear resistance. It is expedient to use a mixture of the said polymers, which reduces the brittleness and prevents the relief image from bursting in the course of its shrinkage on a rigid basis.
  • composition with a destabilizer is given rheological properties that correspond to the operating modes of the printing technology, e.g. correspond to a screen printing
  • a thickener is also an adhesive which improves the connection of the shaped relief to the print carrier.
  • a thickener can also act as a depot that extends destabilizer excretion into the dispersion.
  • the finished product has relief elements with a height of 0.5, 0.8 or 1.2 mm.
  • a polybutadiene styrene dispersion with a disperse phase content of 25% by mass is used as the liquid dispersion.
  • the holding time of the base with the image in the dispersion is 1 minute.
  • the base with the shaped relief is then rinsed with tap water over a period of 5 minutes until the dispersion is removed from the penetration points and allowed to dry at 125 ° C. for 30 minutes.
  • the product obtained has relief points with a height of 0.9 mm.
  • the product is produced similarly to Example 2, but a dispersion of a polypropylene benzene solution in dimethylformamide with a disperse phase content of 20% by mass is used as the liquid dispersion.
  • the finished product has relief points with a height of 0.3 mm.
  • the composition with a destabilizer and the liquid dispersion described in Example 2 are used in the production of decorative products.
  • the relief image is carried out using a composition with a destabilizer using a flow master and allowed to air dry at room temperature for 2 hours, after which the relief image is again carried out on the corresponding image parts using the same composition using the destabilizer and dried the air at room temperature over the course of 2 hours, after which the relief image on the corresponding parts of the image is carried out for the third time using the same composition using the destabilizer and is dried in the air over the course of 2 hours. Then hold the base with the image in the liquid dispersion for 70 seconds.
  • the base with the shaped relief is then rinsed with tap water over a period of 5 minutes until the dispersion is removed from the penetration points and allowed to dry at 125 ° C. for 30 minutes.
  • An ornamental product (a map) is obtained with relief images which have different height values of 0.6 mm, 1.0 mm and 1.3 mm. The product is colored and varnished.
  • the third part of the picture on the basis is carried out by the following composition (in mass%):
  • the proposed invention makes it possible to produce Braille printed matter for the blind.
  • the relief images obtained by the method according to the invention are of high quality with regard to tactical perception.
  • the relief fillets and the variety of possible surface properties, which include roughness and smoothness, hardness and softness, choice of height, color, sterility, adhesive strength on the basis and other properties are ensured by a broad spectrum of polymers that exist in the form of a liquid dispersion .
  • composition can be given a different kind of rheological characteristics with a destabilizer of the liquid dispersion, which can give a flat relief image using any known means, not only using polygraphic methods, but also with the help of a spring, a flow master, one Permit drawing spring or an atomizer.

Abstract

Le procédé décrit consiste à imprimer un dessin plat de l'image sur le support au moins une fois et au moyen d'au moins une composition renfermant un déstabilisant de dispersion liquide, et à traiter ensuite le support revêtu du dessin plat au moyen d'une dispersion liquide. L'image en relief se forme par dépôt de la phase dispersée provenant de la dispersion.
