This invention relates to the ornamentation of paper, cardboard, wood or other surfaces. I v

The objects of the inventIon are to orna ment such surfaces without impairing the same, to secure beautiful and striking color effects at a reasonable cost, without using varnish, expensive oils, gums, injurious acids or the like, 'and without requiring I special equipment or complicated treatment.

These objects are attained by certain novel methods of treatment and combinations of elements as hereinafter set forth and broadly claimed.

One of the special features of the invention is the bringing together on the surface I to be ornamented,- dilferentcolors of vchemitakes place in which the deeper constituents.

of the two colors are thrownioutward and meeting, form a ja ged border, outlining in a general way, t 1e shape of the color areas. These areas may be of irregular out-- line in the natureof splotches or they may be of regular'outline, such as to form stripes or bars, but in each instance, the repulsive action serves toset u a darker border outlining the areas ,an giv ing a heightened color effect. The repulsive action takes place only where the colors come in contact and only while they are, in the Wet state and as I having a bronze or gold. effect. As practical acteristics are most active.

hence while their chemically repellent char- By using difl'erent varieties of colors having these inherently repulsive characteristics, innumerable color combinations can be produced in re ular or irregular designs and with the co. or areas of large or small size, the color fi arcs in each instance being outlined'with a istinctive border giving the tapestry effect.

examples, 'I' combine malachite green with basic'green or blue, acid green with malachite green, basic violet with any of the direct colors. Thus the brilliancy of metalllc effects are produced without using any metallic powders or liquids.

, Toibrighten the effect, a crystallizedv surface may be provided by applyingover the -colors or using with them, a coating ,solutionv made up .for instanceof copper, zinc and stannoussulphates combined withmagnesium sulphate in a solution. ofdextrine or casein, sugar and glycerine. This quickly I dries as a crystalline coating at room teinperature, no special heat treatment being required, and it being, unnecessary to use The crystallization may be'prevented at any point or points on the surface by 'rendering the color used at such point or'points chemically adverse to crystallization as by combining with it, a small proportion of sulphuric, nitric or acetic acid.- In such instance thesech'emically adverse spots re- .main free of crystals while the rest of the surface is covered with the crystalline coatmg. In this ;way itis possible to use the crystals as a b'ackground, outlining other portions.

light reflecting coating sufliciently permanent under ordlnary conditions but it does (paper or other'surface and may be washe ofi with water or other solvent,-leaving the paper smooth'and uninjured.

I have found in my numerous experiments that the acid, basic and direct dyes, and some of the chrome dyes are antagonistic one to another, that is, the acid colors are repugnantto the basic colors, the basic colors are repugnant to the direct colors and even some of the chrome colors are repugnant to each other, in the manner above described, such as by their repellent action to create the irregular boundary lines producing the tapestry effects.

For the crystallized surface, I have used a solution of several metallic sulphates such as'nick'el, zinc,.tin,' aluminum, cupric, com-- bined in dextrine or glue, sugar and glyrerine, with an added quantity of magnesium sulphate or lead acetate; The magnesium sulphate or lead acetate, however, is not essential. The crystallization takes place naturally at practically any temperature and in such a case one of the sulphates is of a more.-or less fugitive character, such .as

zinc and magnesium sulphates, the combination withth'e othersulphate appears to overcome that fugitive character and forms a more lasting crystalline surface which is non-oxidizi g and so not affected by air, retains its iri escent appearance and is not injured by dampness or handling with moist fingers.

The crystallizing compound may be made up as a solution and'applied to the paper or other surface whenever required. The paper ornamented with the tapestry effect or with the crystallized surface, or combinations of both, is adapted for many purposes, such as for covering boxes and the like and the fact that such ornamentation is applicable directly to cardboard makes it possible to ornament cardboard boxes and the like by applying the ornamentation to the cardboard, instead of to a separate paper cover, as has been the practice heretofore.

' By combining several colors in the crystallizing solution, the effects of polarized light can be produced. saidcolors appearing on the surface to which theyare applied as a crystalline light reflecting coating having a -changeable colo'r effect when viewed at different angles or under different lights.

' Whatisclaimed is:

1. The process of ornamenting the surface of paper or other material which comprises applying to such surface, dyes of chemically ,repellent nature in contiguous relation and 4 thereby enabling said dyes in their antago- 'nistic reaction to build up a border of heightened color'outlining the division between the color areas.

2. vThe process of ornamenting the surface of paper or other material which comprises applying to such surface, dyes of chemically nistic reaction to build up a border of heightened color outlinin the division between the color areas an applying to said color areas, a self-crystallizing compgund of metallic sulphates.

3. The process of ornamenting the. surfaceof paper or other material which comprises applying to such surface, dyes of chemically repellent nature in contiguous relation and thereby enabling said dyes in their antagoa border of tallization at certain portions of the surface 4 by previously rendering such portions chem- I ically adverse to crystallization.

4. The. process of producing metallic effects in surface ornamentation without the use of metallic materials which comprises applying to the surface to be ornamented, a combination of dyes having chemically repellent characteristics. Y
