FIELD: printing industry.
SUBSTANCE: invention relates to the dyeing composition for screen printing on the electric and electronic parts as well as for decorative graphics. The composition includes a solvent with the boiling point of 170°C or higher in the amount of 70 wt % or more based on the total weight of the solvent and the prepolymer or a polymer with the molecular weight of 2000 or more in the amount of 2 wt % or more in the total composition. The composition has viscosity ranging from 30 to 180 Pa⋅/Sec at 25°C and the thixotropic index within the range from 2.0 to 8.0. When using a screen printing plate with 360 cells per inch (14 cells per 1 mm), which is formed by a high-strength non-deforming stainless steel mesh made of wire with a 25 mm diameter, the width of blurred edges of the printed image does not exceed 10 microns from the specified size of the image's printing plate.
EFFECT: one-step production of printed products, with inclusing of detailed images and solid figures of large area of high quality and resolution, with no spreading or flaking with sharp edge sections of the image on solid figures and an increased leveling capacity.
