Abstract
Abstract A method of producing a design by applying translucent coloring material repellent by means of a writing -instrument to an inkabsorptive surface of a sheet support, said repellent comprising polyalkyl siloxane in a volatile liquid medium which evaporates to leave the design, and thereafter applying a washable ink, water color or spirit soluble ink to color the sheet and to provide a contrasting color background against the design made by the writing instrument. The sheet may be coated with the repellent and coloring material before the written design is applied. The repellent may contain a coloring material which aids in creating different colors in contrast to each other.
