Definitions

  • This invention has for one object to provide a method for imparting a translucent or comparable surface to sheeting. Another object is to provide an improved chemical-physical process for treating sheeting whereby controlled translucent or matte effects may be secured on the surface of such sheets. Still another object is to provide a process of the class indicated which does not necessitate the permanent incorporation of foreign components in the sheeting. A still further object is to provide a new translucent type of sheeting wherein the surface of the sheeting imparting the translucency has a relatively uniformly changed surface but is still comprised of the same chemical materials as the remainder of the sheeting. Still another object is to provide a translucent sheeting which is of a character readily susceptible to scrap recovery therefrom. Other objects will appear hereinafter.
  • FIG. 1 represents a roll of sheeting, the surface of which is to be given a matte treatment in accordance with the present invention.
  • This roll of starting material is supported in any conventional manner so that it may be unrolled in the direction of the arrow over the several idler rollers 3, 4, 5 and 6.
  • the cleared sheet is conducted from roller 32 into another chamber 35 of a construction substantially identical with chamber 12 already described; That is, the chamber 35 is provided with inlets and outlets36 and 37 for a suitable heating or drying medium supplied to or withdrawn from chamber 35. Chamber 35 is provided with openings 38 and 39 whereby the sheet material may be introduced into the chamber and withdrawn from the chamber.
  • the interior of the chamber is provided with a plurality of rollers such as at 41 for suitably looping the sheet within the chamber for best exposing it to the drying or curing medium.
  • the finished sheet leaving through opening 39 passes over one or more rollers as at 42 and is then wound up in a conventional manner at 45. In order to move the sheeting through the apparatus, roll 45 will be power driven.
  • the apparatus of Figure 1 illustrates one type of arrangement which may be used for the continuous carrying out of my invention.
  • FIG. 2 there is shown on a scale of magnification of the order of300 times what a photomicrograph of a cross-section of my sheet would appear as when emerging at point 16.
  • the product is made up of a base portion 46, the surface and sub-surface of which contain numerou's -gas pockets as shown at 47.
  • Example 2 In accordance with this example, a pigmented cellulose ester sheeting pigmented with a small amount of titanium dioxide having a glossy surface was processed in accord ance with my invention to provide a translucent surface thereon.
  • This pigmented sheet which was in thickness, was overcoated with a coating composition similar to the composition set forth in detail under Example l, with the exception that the decomposable salt was comprised of ammonium bicarbonate.
  • the ammonium bicarbonate was of a commercially obtainable technical grade and of the usual powdery nature.
  • the pigmented sheet thus overcoated was dried and the bicarbonate decomposed in a chamber such as the chamber 12 described in connection with Fig. 1.
  • a pigmented sheet having a translucent nonglossy surface was obtained.
  • This surface was partially cleared by treatment with a clearing solution comprised of a small amount of acetone diluted with water.
  • a clearing solution comprised of a small amount of acetone diluted with water.
  • the degree of clearing the surface of the sheet can be controlled by the choice of the solvent used for the clearing solution.
  • hat is, for example, an 8020 mixture of acetone in water will fairly rapidly and deeply attack a cellulose ester sheeting.
  • methanol alone may be regarded as milder in action.
  • Example 5 there was treated a cellulose ester sheeting of the type used in the photographic industry for movie film leader. That is, on movie film there is provided what is known as a leader strip at the start or finish of the roll of film.
  • This leader strip which prior to the present invention has been comprised of highly pigmented film stock, has for one purpose to prevent high glare from the projection screen at the start and finish of a reel of film.
  • an entirely transparent leader strip is employed, there is practically no obstruction to the light of the projector passing therethrough. This would cause undue illumination on the screen at the start or finish of the projection of movie film. Therefore, it is desirable to provide some sort of a leader strip on the ends of the film exhibiting a density in excess of .3.
  • the photographic base sheet thus overcoated was subjected to :drying, heating for decomposing the salt, etc., to produce a composite photographic sheet having a translucent surface without the necessity of incorporating ground glass.
