Definitions

  • the present invention is concerned with a method of printing the surfaces of synthetic polymer materials.
  • Silk screen printing has the disadvantages that it is difficult to obtain accurate registration and fine definition
  • transfer printing has the disadvantage that a different pigment is required for each colour required in the final printed design: for a multi-coloured design, many pigments, for example, up to 16 different pigments, may be required. For each different pigment, a separate printing roller is required and the use of such a large number of printing rollers causes severe difficulties in obtaining colour registration.
  • OMPI _ design penetrates into the surface of said polymer body- such that it cannot be erased by solvent action or mechanical abrasion without destruction of said surface.
  • the method according to the invention may be a four-colour printing process, which involves making four colour-separation negatives from the desired design by means of colour filters (the four colours being, for example, magenta, yellow, cyan and black), preparing corresponding printing plates from each of the colour-separation negatives and printing on the polymer surface using each of the resulting printing plates, in succession and in register, using an appropriate ink for each printing plate.
  • colour filters the four colours being, for example, magenta, yellow, cyan and black
  • print ⁇ ing plate includes other printing surfaces, such as printing rollers.
  • the four-colour process has, until now, only been used for printing on the surfaces of paper, paper articles, and the like.
  • the or each printing plate used in the method according to the invention is preferably gravure, lithographic or flexographic; the or each printing plate may be prepared
  • the polymer which is printed according to the invention may be in any suitable physical form, such as in the form of a 3-dimensional moulded article or in laminar form (such as a film, sheet, coating or textile fabric).
  • the polymer when it is in the form of a film, sheet or moulded article, it may be made of a thermoplastic polymer, such as a polyester, nylon, poly ⁇ propylene, polystyrene (including high impact polystyrene), an acrylic polymer, a polycarbonate > polyvinyl chloride, a cellulosic polymer, or a therraoset polymer such as
  • the polymer may, when in the form of a moulded article, contain conventional reinforcement, such as, for example, glass fibres.
  • Such polymers may also be used in the method according to the invention in the form of a coating on, for example, wood, hardboard, chipboard, laminated plastics, metals (such as etched metals or anodised aluminium) or ceramics.
  • the polymer When the polymer is in the form of a coating, it may have been applied, for example, by spraying (e.g. electrostatic spraying) or curtain coating; the coating may be a stoved coating.
  • spraying e.g. electrostatic spraying
  • curtain coating When the substrate is a ceramic article (such as a ceramic tile),curtain coating is preferred, whereas when the substrate is a metal, electrostatic spraying is preferred.
  • the polymer printed according to the present invention is a textile
  • it may be, for example, of polyamide, polyester, and acrylic polymer, or poly ⁇ propylene.
  • the polymer when the article being printed is a textile, then the polymer may comprise a natural polymer, in addition to, or instead of, a synthetic polymer. Examples of such natural polymers include wool and cotton textiles.
  • Such textiles may, for example, be in the form of woven fabric, knitted fabric, or even open mesh net.
  • the coloured inks used in the method according to the invention preferably comprise dyes or pigments in an oil or resin base; solvent free inks are sometimes preferred. Examples of suitable inks are available commercially from Coates Brothers under the designation Lithotex 137 17/220. Such inks have good colourfastness an l are resistant to washing, perspiration, dry cleaning ) rubbing and gas-fading.
  • the elevated temperature employed is preferably from 100 to 220°, more preferably 110 to l8 ⁇ °C. Higher temperatures in the above ranges can be employed when the polymer is relatively thermally stable (such as a polyurethane) or in the form of a coating on a thermally stable backing (such as PVC or a polyurethane on a thermally stable fabric backing) .
  • the pressure employed may be from 1 to 400 psi , preferably from 50 to 200 psi . Lower pressures are generally employed for thinner polymer substrates and higher pressures for thicker substrates. For example, a pressure as low as 1 psi can be used when printing a very thin PVC film, such as one having a thickness as low as 12. or where low gloss is wante
  • the polymer substrate can be laminated to another polymer layer at the same time as the printing process according to the invention is carried out.
  • the printing may be carried out by a transfer process as an alternative to the four-colour process described above.
  • a glossy finish can be applied to the print by the use of a glossy transfer oaper and/or by the use of glazing rollers.
  • the plasticiser should not be such as to allow too much migration of dye away from areas to be printed. Accordingly, when the polymer is PVC, it desirably is not plasticised by means of styrene-butadiene copolymer.
  • a polymer body which is printed according to the invention may act as a support for the printed design
  • OMP ⁇ printed body being bonded to an article it is wished to decorate, either with the printed design on the polymer surface facing - the article to be decorated (in which case the polymer would, of course, be transparent) or with another surface adhered to the final substrate.
  • the method accord ⁇ ing to the invention results in printing, not just on the surface, but penetration of dyes into the layer adjacent the surface, making the resulting printed designs more permanent than those obtained in prior processes (that is, the printed design cannot be erased by solvent action or mechanical abrasion without destruction of the polymer surface) .
  • One surface of unsupported PVC film was heated by a heated press plate at 110°C for a dwell time of 80 seconds and a pressure of 200 psi, and the other surface thereof was printed by a four-colour printing process.
  • Example 1 was repeated using a dwell time of 50 seconds and a pressure of 100 psi, the printing being litho- graphic using two colours. Good colour reproduction and print clarity was obtained.
  • Example 3
  • Example 1 One surface of unsupported PVC film was heated by a heated press plate at 150°C for a dwell time of 30 seconds and a pressure of 100 psi. The other surface was screen printed in multiple colours; excellent colour reproduction and print clarity were obtained.
  • Example 5 Example 1 was repeated, using a temperature of l60°C and a dwell time .of 40 seconds; similar results were obtained.

  • PVC coated cotton fabric was pressed on the cotton surface by means of a press plate atll0°C for 50 seconds and 40 seconds, respectively, using a pressure of 100 psi.

Abstract

Un dessin en couleurs est imprimé sur une surface polymère (de préférence par un procédé d'impression à quatre couleurs) de telle sorte que le dessin pénètre dans la surface polymère et ne peut être effacé par l'action d'un solvant ou par abrasion mécanique sans détruire la surface. Le polymère se présente de préférence sous la forme d'une feuille, film ou revêtement et la surface non imprimée est soumise à une température élevée avant ou pendant l'application du dessin imprimé.
