ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of drawing on a paper sheet linear figures such as pictures, letters and characters in such a manner as producing therein a peculiar visual effect.
2. Description of the Relevant Art
The linear figures such as pictures, letters and characters are usually drawn using some writing tools including ball-point pens, fountain pens and line-markers, or using certain painting tools including so me painting or calligraphic brushes and crayons. These tools known in the art will generally give pictures and/or characters that are composed fundamentally of simple and monochromatic lines.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a method of drawing linear figures such that a novel and epoch-making visual effect is produced in the figures.
The method developed by the present inventors so as to give such a fresh visual effect to the drawn figures does comprise the steps of applying at first an ink to a paper sheet by using an ink applicator so as to form raw figures on the sheet, with the ink containing at least two colorants that include pigments and dyestuffs and are different in their adhesional strength of sticking themselves to the paper, and subsequently scrubbing the raw figures along a desired linear contour.
At the first step in the present method, the applicator will apply the ink to the paper sheet, and the ink comprises the two or more colorants that may be any pigments and/or dyestuffs.
Such a preliminary application of the ink may be done uniformly all over a desired area on the paper sheet, or alternatively in a manner to write letters or characters or to draw figures of a substantially linear pattern.
At the next step, areas, regions and/or zones in the letters, characters or figures thus written or drawn will be scrubbed with a proper means, along a desired contour or over a desired pattern. Preferably, the scrubbing or scouring means may be a rubber eraser. Although this eraser can be moved manually along any imaginary locus but without aid of any rules or formulating tools, it is recommended to use an appropriate formulating plate such as a writing or erasing templet (often called ‘template’). This templet will intervene between the paper sheet and the scrubbing or scouring rubber eraser.
As mentioned above, the upper surface of the ink layer formed on the paper sheet will be scrubbed, wherein the ink contains two or more pigments and/or dyestuffs blended therein and mixed with each other. Therefore, one or more such colorants having a lower adhesional strength and weakly sticking to the paper will be removed therefrom by the scrubbing. The other colorants having a higher adhesional strength and firmly sticking to the paper remain thereon, so that a locus of the rubbing motion will appear as a linear pattern, design or figure.
The ink applicator used herein may preferably be a ball-point pen or a marking pen. The ink having blended therein the two or more kinds of colorants of different adhesional strength and preferably being stored in the applicator may preferably be any one or ones of metal powder-containing inks, double color-developing inks and pearl-glossy pigment-containing inks.
In the method of the present invention, the applicator is the ball-point pen or marking pen that is filled with the ink so that it can be applied to a paper sheet in the same manner as writing ordinary letters or characters or as drawing any designs or pictures. This ink is, as mentioned above, a metal powder-containing ink, a double color-developing ink or a pearl-glossy pigment-containing ink.
If the metal powder-containing ink is used, a limited amount of the metal powder in the ink will be eliminated from an area or region scrubbed with a rubber eraser or the like. The other dyestuffs and/or pigments in the ink will however not be removed from but will remain on the area of the paper sheet.
If the pearl-glossy pigment-containing ink is used, a limited amount of the pearl-glossy pigments in the ink will be eliminated from an area or region scrubbed with a rubber eraser or the like. The other dyestuffs and/or pigments in the ink will however not be removed from but will remain on the area of the paper sheet.
In the case of the double color-developing ink, a central zone of an ink stroke will become glossy or brilliant to give a surprising ornamental effect, if scrubbed with the rubber eraser or the like.
A proper amount of certain thixotropic polysaccharides or any derivative thereof may be added as a thickener to the ink containing the two or more dyestuffs and/or pigments which stick to the paper sheet with different strengths.
It is a matter of course that the present invention can be applied to any plane article other than paper sheets to be coated with the ink.
The present invention also provides a tool assembly for performing the method described above, wherein this assembly will comprise an ink applicator and a template. This applicator stores therein the ink containing a metal powder pigment mixed with a dyestuff sticking to a paper sheet with a higher strength than the former, and that template has at least one hollow region such as holes and cutouts of any desired configurations. Those ink applicator combined with the template for drawing desired figures may be packed in a container such as a box or bag.
Thus, the ink applicator and template both placed in the container of the tool assembly are ready for cooperative use to draw any desired linear figures.
The container may accommodate an ink-scrubbing rubber eraser in combination with the ink applicator that dispenses colorants sticking to the paper sheet with different adhesional strength. It may also be possible for the container to accommodate all the three tools, that is the ink applicator, the template and the ink-scrubbing rubber eraser, for better convenience to users.
