ATTU R N EYS Dec. 15, 1953 K. SHREEDHARAN EXPOSITION WATER COLOR PROCESS 3 Sheets-Sheet 3 Filed Dec. 5, 1948 L I INVENTOR. fi&%aj6/wve%mg Patented Dec. 15, 1953 UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to the general class of ornamental coating processes of the pigment surface type, and more specifically to an exposition water color process of recording and reproducing letters, designs, pictures, words, symbols, Written documents, advertisements, etc. upon a card or other plain surface material, and manually employing a scriber, stylus, stencil, paint brush, or other suitable means in carrying out the steps of the process.

By the utilization and variations in the steps of my novel process, and without requiring the use of chemicals, originals are produced by exposing in a uniform layer of a suitable opaque pigment in a water vehicle the required lineforms for the facile working of a color scheme that is capable of producing novel originals in water color painting.

A recorded original may artistically be built up and finished upon an opaque, transparent, or translucent backing or base, for a card, having a smooth surface that is adapted to receive and record an impression in wax-lines or forms created by the use of a stylus, or stencil, from a waxed transfer sheet. The wax impressions, lines, or forms may also be created by tracing, with a stylus, an original design or symbol, through the waxed transfer sheet to the backing; and a brush, usually by single strokes is employed to lay various colors of an opaque pigment, or water color, upon the cero-graphed surface of the backing or base.

The invention consists essentially in an artistic creation of a color process based upon the nonmiscibility or non-mixing of oil and water, and in which an oily wax transfer sheet, as of paper, is employed in transferring or translating cerolines or forms to a receiving sheet or backing, and the cero-lines are subsequently exposed to view by brushing on the backing a coating of suitable water-soluble color or colors. Various shades or tints of metallic sheets, or strips of foil, as silver, may be applied to the base or backing to coact with the cero-lines and water colors in producing high lights in an ensemble. means the finished artistic creation may have a luminous white or bright surface; a glazed surface; a surface having mild and metallic lustrous lines as well as a brilliant metallic lustre;

and plain or colored lights may be employed to illuminate the exposed cero-lines.

In the accompanying drawings I have disclosed a complete example of a physical embodiment of the steps in my color process, but it will be understood that changes and alterations By this 2 are contemplated, and may be made in these steps, within the scope of my appended claims, without departing from the principles of the invention,

In the drawings:

Figure 15 is an edge view of the card in Fig, 14 showing the use of the transparent sheet of Fig. 4 mounted on the backing sheet of Fig. 3, and provided with water colors as in Figs. 5, 6, 7, and 8.

Figure 16 shows a portion of a card bearing the letter C, and made up of layers of transparent paper or foil, cero-lines, opaque water paint, and indicating by arrows in Fig. 17 the transmission of light through transparent spaces; and Fig. 17 is an enlarged sectional detail view at line l'!l1 of Fig. 16.

Figure 18 shows a card including a backing 3 sheet, the foil strips of Fig. 10, and shading of opaque paint colors or pigment; and Figure 19 is a sectional view at line |9-l9 of Fig. 18.

Figure 20 is a view of the card and design shown as in Fig. 9 covered by the transparent (or translucent) sheet of Fig. 4 with the brown, green and red colors properly finished; and Fig. 21 is an edge view of this card.

Figure 22 discloses the transparent sheet of Fig. 4 and the painted colors on the back of the sheet behind the wax lines; and Figure 23 is an edge view of this card.

Figure 24 depicts a card bearing a butterfly designed in the colored foil strips of Fig. 10, upon the transparent sheet of Fig. 4; and Figure 25 is an edge View of this card.

Figure 26 is a view of the back of the card in Fig. 24 with the backing sheet and certain parts removed; and Figure 27is a detail of the part shown in Fig. 5 cut for use in the design in Fig. 26.

As one complete example of my exposition process in the production of a sample card illustrated in Figs. 1 through 14, for depicting the steps in reproducing the ornamental color scheme from an original word charming, I employ a thin transfer sheet of paper I faced with a coating 2 of hard oily wax indicated in Fig. 2. For this purpose a comparatively hard paraifin wax, hard tallow, or other oily wax is applied to the sheet, from which cero-lines, or wax lines will be made having the required 011 consistency to repel water, and thereby prevent adhesion of the paint pigments carried in the water colors.

This waxed transfer sheet I is placed, waxed face down, upon a second sheet 3 as a backing or base having preferably a plain or a glossed surface, as in Fig. 3; or a backing sheet 4 in Fig. 4 may be translucent or transparent, upon which the word charming, is to be painted in various water colors.

An original tracing sheet, as of transparent paper 5 in Fig. 1, and bearing the word to be reproduced is now laid over the back of the inverted Waxed sheet I, and a comparatively blunt stylus or scriber, or other suitable instrument, is manually employed in tracing the letters of the original and thus transferring the letters and reproducing them in cero-lines, or wax lines, as 6, upon the base or backing sheet 3 or upon the transparent sheet 4. The wax lines are designated by the numeral 6 throughout the draw- 18's.

The tracing sheet is now removed, together with the waxed transfer sheet, from the backing sheet leaving the cero-lines or letters outstanding on the base or backing sheet, and a body color, or colors, as a water color coating is applied by strokes of a brush to the backing or base. The various body colors are indicated as I in Fig. 5, or as 8 in Fig. 6, or as l5 in Fig. 7, and in Fig. 12 an opaque water color, as 9, is illustrated.

The color, or multi-colors are quickly applied with strokes of'a brush, and the water paint is thus spread evenly and smoothly to insure a uniform body thickness of paint upon the base,

without however coating the cero-lines or letters with the paint, and thus preventing adhesion of the paint pigments to the wax letters.

Inasmuch as the process is based upon the non-miscibility,. or non-mixing of oil in the opaque water colors with the wax of the letters or cero-lines, the failure of the pigments to adhere to the wax letters causes these letters or cero-lines to be exposed and brought into view with distinct clarity upon the card of Fig. 12 and in contrast to the body color of the card.

In Fig. 14 a portion of the charming card is shown with a transparent finishing sheet 4, as of cellophane, superimposed upon the base or backing 3, as a protective cover for the varicolored paints or pigments at I, 8, and I5 in Figs. 5, 6, and 7. Or, if desired a sheet of gold foil, as IS in Fig. 8 may be covered by this transparent sheet 4.

Figs. 9, 20 and 22 disclose the process in which Valex water colors are employed in preparing the surface of the backing or base sheet for exposing to view a plant bearing red fruit or berries, green leaves, and green stems. The roughly prepared design is painted upon the backing sheet 3- Fig. 3 and is shown in Fig. 9; and Fig. 22 shows the design upon the back of a transparent base sheet as 4 in Fig. 4. In the completed card of Fig. 20, after the necessary line-forms of wax have been recorded on the required spots and spaces, they have been exposed to view by brushing a uniform layer or coating of opaque pigment, or water-color. The transparent rough colors in Fig. 9 have been trimmed to insure and expose exact lines, forms, and designs, to the sight.

In Figs. 24, 25, 26, and 27, there is shown a transparent sheet having thereon a butterfly design which is formed by a combination of the elements shown in previous figures.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A coating process comprising transferring wax lines from a tracing sheet to a base, next removing the tracing sheet, and then applying a water solution of an opaque pigment to the base.

2. The process of claim 1, and further including the step of applying a transparent covering over the base.
