LEON LIIIJIENFELD, or VIENNA, AUSTRIA-HUNGARY. PROCESS OF Paooucme METALLIC R LUSTROUS COLORS FOR PRINTING 0N AFABRVIJCS.

Be it. known that I, LEON LILIENFELD, a subject of the Emperor of Austria-Hungary, residing in Vienna, Austria-Hungary, have invented a new and useful Process of Producing Metallic or Lustrous Colors for Printing on Fabrics and theLike; and- I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to make and use the same. I

The production of metallic or lustrous printing effects on textile fabrics has hitherto presented apparently insurmountable difliculties in consequence of the want of suitable fixing media sufficiently impressionable for the purpose and at the same time capable:

' of resisting physical and chemical influences.

The principal advantage to be fulfilled is when the fabrics are brushed or beaten or washed with Water, soap, alkalis, acids, &c.,

, the metallic powders or pigments producing metallic or lustrous effects adhere sufficiently toz the fabrics without the pliancy of the fabrics being affected; I 'The'fixing media hithertoemployed have not met this condition. They are, moreover,

lacking in that they do not'bring out the printing effects in, clear, sharp outlines, require longer time than is desirable for drying, and can only be used on dark-colored fabrics,

been hitherto so apparent.

The fixing media used in carrying out .this process compnse a resinous substance, avegetable-juice substance, and-wood-oil. Oneor more sultable resinous substances are first melted, finely divided india-rubber or guttapercha being introduced into the melted ma- .terial and the heating continued until a uniformly-melted substance'is produced. This melted substance ormixture is then .at once or when cooled dissolved in a suitable solvent-such as benzin, chloroform, disulfid Specification of Letters Patent. I

unserviceable in: every respect, while, on the other hand, the printing solutions obtained with the same quantities following the'above named rocedure produce faultless printing effects, w ence it isproved that in the melting of 'the india-rubber with resinous substances un'-' der heatachange in the one or the other iseffected which is favorable to the intended purpose. .The precise proportions for the mix ture cannot be given, as they may be varied to the greatest extent. Next, I mix together wood oil and a resinous substance, with'the aid of heat to melt them,if desired; This "mixture (sometimes commercially known as rhusol) is then treated with a suitable solvent-such as tupentine, benzin, drier-oil, &c,and then, being meantime filtered or not, mixed with the first-named mixture and thepigment. The result is a solution whereby more perfectly iron-fast metallic printing effects and greater quickness of ratemsea March 20,1996.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The process of producing metallic or lus-' trous colors for printing on fabrics and the like which consists in mixing together a resinous substance and a vegetable-juice substance, combining with said mixture a mixture comprising Wood-oil and a resinous substance, and then. adding to the mixture thus formed the pigment, substantially as described.

In testimony that I claim the foregoing I have hereunto set 'my hand this 28th day of LEON LILIENFELD. Witnesses x L. H. 'MUNIER, Homer; LEE WAsmNo roN.
