Description

ranv'rma nut. 1,410,572. maxim mm n Patented Mar. 28,1922. n Drawing. Application me m 20,1021. amino. 486,193, 2 2 f To all whom it may concern:
Be it known that I, KIYONAO Isuma, a subject of the Emperor of Japan, residing at No. 2 of 135 Oaza-kamishibuya, Shibuya- 5 machi. Toyotama-gun, Tokyo-fu, Japan, have invented new and useful Improvements in Printing Ink, of which the following is a specification.
This invention relates to a method of manufacturing a printing ink by mixing together lamp black, mineral oil, rosin, catechu. formaldeh 'de. alka Iine silicate 51E;-
ine carbonate. ggm grab 1c, insoluble sb a and water. the ob j'ect b ing to supply a printing ink never smearing papers, nor affecting rolls. so as to secure clear print, its thickness being made adjustable by water admixture.
Among the important qualities a printing ink should have. are counted suitable adhesive power and consistency. If too adhesive. the ink tends to conglomerate and does not spread evenly over the surfaces of rolls, tyJes. or apers, causing thereby various hitc es in t e printing process. If not sufiiciently adhesive, the ink is liable to be pressed from between types and papers, thereby smearing the print. If too .consistent or tough, the ink is not easily absorbed by papers so that the printing speed has to be reduced in order to get clear print. If not suflicientlyconsistent, however, it will penetrate too deeply into the tissue of the paper and smear it.
be present invention intends to be a new improvement in these respects. The adhesive-power as well as the consistency is so made as to be regulated by add' suitable quantit of water according to c fianges of 40 atmosp eric temperatures or qualities of papers used, while the ink is so prepared as not to affect rolls.
A practical numerical example of the pres.-
ent method is given below:
Lamp black 100 lb. Mineral oil 1000-2000 osin -200 Catechu 5-10 50 Formalin 2-10 Sodium silicate 10-100 Sodium carbonate Gum arabic suitable quantity Aluminium resinate or other aluminium s0ap-- small quantity Colouring matter small quantity @Vater, 500-2000 To combine these ingredlen we first mix rosin with mineral oil; boil the mixture, adding later lamp black. Knead the same with rolls several times, and then add'thereto another mixture composed of the rest of the ingredients. Thus the ink is obtained.
Colouring matter here to be used serves to give lossy lustre to the black ink, the black c0 our being produced from lamp black. For coloured inks, other than black, lamp black is dispensed with, and colouring matter alone is used to produce the required colour. The chief colourin matter used for these purposes are Prussian blue and meth l violet etc.
Sodium sllicate serves to make the ink easy to spread, and besides, in conjunction with gum arabic, it serves to keep oleic ingredi cuts and water fused together in state of emulsion.
' Examine Aluminium soap supplies cohesive power to mineral oil, and keeps that power from changing according to atmospheric temperature, it also gives lustre and water-repelling power to the printed surface.
osin increases the cohesive power of mineral oil and also supplies consistency.
Catechu tends to prevent smearing and increases lustre of the printed surface and enables the surface to stand friction.
To formalin we owe the durability of glutinous rolls.
These ingredients, however, may be substituted by other similarly acting substances.
Thus it will be seen that the present method is characterized b supplying tan- .nin, soluble silicate, insolu le soap, formaldehyde, and gum arabic to the soap composed of lam black, mineral-oil, resin, etc., thereby enab g the ink to combine and mix with .water with the result that the adhesiveness or viscosity of the ink can be regulated b adding water, which is a eat merit. us the ink can spread itsel easily over surfaces; is equally adhesive; never smears papers; lossy black (or other coloured) with ma quantity; the printed surface clear; figures .or scenery as vivid as if m relief; never wearies the eyesthe t pe'surfaces and papers easily separable an so that printing speed is gained. Claims: I
1. A print ink composed of colouring matter, minera oil, resin, soluble silicate, water-insoluble soap, a material containing tannic acid, gum arabic and formaldehyde.
2. A printing mk composed of colouring matter, mineral oil, resin, soluble silicate,
water-insoluble soap, catechu, gum arabic and formaldehyde.
3. A printing ink comprising mineral oil,
5 resin, catechu, formaldehyde, sodium silicate, alkaline carbonate, gum arabic, aluminium soap, colouring matter and water, substantially as and for the purposes hereinbefore set forth.
In testimony whereof I have signed my 10 name to this specification.
