Description

one

This invention is applied to the field of printing industry, namely to screen printing ink used for printing on binding materials on paper base with polyvini chloride coating such as Nevsky, Bumvinil, Balakron, polyester, pressed to cardboard, cellophane, promotional and souvenirs polyvinyl chloride based polymer films, lederin, artificial leather, as well as for marking polyvinyl chloride products such as polyvini chloride plastic and vinyl leather.

A screen printing ink containing 10-15% by weight of a copolymer of vinyl chloride with vinylideachloride or vinyl acetate, 5-15% by weight of pigment, 2-1% by weight of filler and the remaining organic solvent tetralin or ethyl cellosol in lj is known.

The disadvantage of this printing ink is low color fastness and abrasion, amounting to 1 O-69 ps.

depending on the type of material treated, as well as its toxicity and stickiness. In addition, during storage, the paint is stable only for 6 months.

The purpose of the invention is to increase storage stability and resistance to abrasion, as well as to eliminate stickiness and reduce toxicity. ,

This goal is achieved due to the fact that in the known paint the binder additionally contains a copolymer of amide tetraacrylic acid with butyl ether of methacrylic acid, and as an organic solvent is a mixture of benzyl acetate, acetoacetic ester and ethyl cellosolve or butyl (di) glycol in a weight ratio of 2.585: 2 , 5-85: 1О-83,7 with the following content of components, wt.%.
