Abstract: 551,183. Photo-mechanical printing-surfaces. CO-OPERATIVE WHOLESALE SOCIETY Ltd., and TILL, L. A. July 9, 1941, No. 8660. [Class 98 (ii)] [Also in Group XV] A process of producing a printing surface as by photoengraving from an original of the kind prepared by printing on a paper or like sheet a stipple of lines, dots &c. in invisible ink, making on the sheet a drawing of the matter to be reproduced, and treating the sheet with an agent which renders the stipple visible at the areas where. it is desired, is characterized in that the invisible ink stipple markings have additional markings of smaller area printed over them in a different invisible ink or in a resist medium in order to permit selection of intensity of stipple. The stipple markings may all be printed in invisible ink as shown for a single element at X, Y, Z, Fig. 4, the upper markings being progressively smaller and capable of removal in turn by application of solvent before the selected set is rendered visible; or each marking may comprise an area X printed in invisible ink protected with one or more different resist coatings Y, Z, e.g. collodion and gum, which may be washed off selectively so as to lay bare only certain areas of the invisible ink markings before treatment to render them visible. The expression invisible ink includes any ink which will not reproduce in the photo-engraving process. Examples of invisible inks, with the appropriate developers in brackets,' are : lead base paint (sodium sulphide), nut galls and calcined sulphate of iron (water), ferric sulphate (nut galls or potassium ferrocyanide), copper sulphate (potassium ferrocyanide), cobalt nitrate (oxalic acid), Fowler's solution (copper nitrate), and soda lye or sodium carbonate (phenolphthalein); the inks may be mixed with binders such as gum arabic, varnish, spirit, or. cellulose compounds; and the developers may be applied as with a brush, glass pen, or rubber rod, or may be put up in solid crayon form.

Title: A method of manufacturing mouldings of polyvinyl chloride resins having excellent mechanical properties
IPC: C08F259/04
Filed: 1965-03-05
Abstract: A shaped article of vinyl chloride resin is formed by a method in which a diene monomer alone, or a mixture of 99 to 30% by weight of a diene monomer and 1 to 70% by weight of a styrene monomer, with or without a third monomer, is grafted on to pulverulent vinyl chloride resin by means of ionizing radiation, to give a graft vinyl chloride resin containing from 2 to 30% by weight of the grafted components, and the graft resin is milled at a temperature within the range of 100 DEG  to 200 DEG  C. and shaped by moulding.  The vinyl chloride resin, which may be a homopolymer or a copolymer of a major proportion of vinyl chloride with a minor proportion of a vinyl ester or vinyl ether, is subjected to irradiation either before or during contact with the monomers. The third monomer is, e.g. a derivative of acrylic or methacrylic acid, or acrylonitrile.  In the examples, polyvinyl chloride is irradiated with an electron beam prior to being placed in a methanol solution of butadiene, butadiene-styrene, isoprene, isoprene-styrene, or butadiene-a -methyl styrene and carrying out graft polymerization.  Similarly, a vinyl chloride-vinyl cetyl ether copolymer is grafted with butadiene or butadiene-styrene. In other examples, polyvinyl chloride is immersed in a methanol solution of butadiene or butadiene-styrene and irradiated with CO-60 gamma-rays to produce the graft polymers.  The products are mixed with components selected from ungrafted polyvinyl chloride, polybutadiene, tin mercaptide, butyl stearate, barium stearate and dioctyl phthalate prior to being milled and moulded
