Title: Improvements relating to aminotriazine-aldehyde resins
IPC: C08G12/34
Filed: 1948-03-10
Abstract: A resinous composition comprises an aminotriazine-aldehyde reaction product, modified by introducing into the reaction a monoamine having two aromatic nuclei, or by reacting the aminotriazine condensate with a resinous product produced by reacting such a monoamine with part of the aldehyde, the amount of monoamine used being less than one molecular proportion of amino-triazine.  Specified monoamines are a - or b - naphthylamine, and amino-diphenyls, e.g. o-amino-diphenyl.  In examples, melamine and formalin are reacted and in (1) ortho-amino-diphenyl, and in (3) a -naphthylamine is added, and the mixture reacted further.  In (2) an o-aminodiphenyl formaldehyde resin and (4) a b -naphthylamine-formaldehyde resin is blended with a spray-dried melamine-formaldehyde resin.  The products are mixed with silica flour and zinc stearate, ground, and moulded.  In example (5) o-aminodiphenyl and formaldehyde are reacted, and the condensate further reacted with melamine and more formalin.  The product is mixed with a -cellulose and zinc stearate, and the slurry is spray-dried.  In example (6) furfural is added to the mixture of example (5) to prevent crumbling of the resin when worked on rolls. A moulding composition comprises 45 parts resin of example (6), 41 parts anthophyllite asbestos, 13 parts cotton flock, 0.45 parts benzoyl phthalimide, 1 part zinc stearate.  Specification 591,496 is referred to.  The Specification as open to inspection under Sect. 91 states that compositions may be obtained by blending a melamine-formaldehyde resin having a high molar ratio of modifying agent with an unmodified (or less modified) melamine-formaldehyde resin in quantities to provide a final composition containing the proper ratio of modifying agent to melamine in the total blend.  This subject-matter does not appear in the Specification as accepted.

Abstract: 637,105. Printing-surfaces. LUDVIGSEN, N. March 20,1947, No. 7671. Convention date, Jan. 17. [Class 100 (ii)] A method of manufacturing copy printing blocks from an original printing block comprises pressing, by means of a reverse die made from the original block, layers of materials of different colours, the layer adjacent to the die partially filling the hollows of the die so that the relief parts of the copy block are differently coloured from the hollow parts. A die 1 made from an original block is placed below differently coloured sheets 2 and 3 of material such as celluloid, impregnated cardboard, or an agglomerated substance such as resin, bitumen or fine sawdust. The sheet 2 has a thickness e equal to or less than the height h of the relief portions of the die 1. Pressure is applied to the sheets by a plate 4 so that the relief portions of the die 1 penetrate the sheet 2 and the two sheets become united together. The hollow portions 5, Fig. 2, of the block produced are of a different colour to the relief portions 6. In place of the sheets 2 and 3 layers of differently coloured powdered material may be used, the two layers becoming agglomerated under the combined action of heat and pressure. Alternatively, one sheet and one layer of powdered material may be used. In a modified method the die may be superficially coated in parts with colouring matter and a single sheet of material is then pressed on to the die.
