The closest analogue is a varnish containing a solvent (see, for example, the description of the patent RU 2045558, IPC C09D 133/10, date of publication, 10.10.2005,).

The technical result of the claimed solution is to reduce the stickiness and improved bonding ability.

The essence of the technical solution is characterized in that it contains a solvent comprising methyl ethyl ketone and toluene, antistatic additive, which represents a cationic compound, halogen-free, which is based on the solution of Quaternary ammonium, built-in polymer media, dissolved n-butanol, and the synthetic resin in the form of a copolymer of methyl methacrylate with TM Tg=124°C. and a dynamic viscosity of a solution in toluene 1500 MPa·s in the following ratio (%):

As a copolymer of methyl methacrylate with TM Tg=124°C. and a dynamic viscosity of a solution in toluene 1500 MPa·s can be applied low melting acrylic resin Degalan M 825, soluble in ketones, esters and aromatic solvents. Its application provides improved bonding ability of the claimed adhesive varnish for PVC. Low-melting acrylic resin Degalan M 825 manufactured by the firm "Degussa" (see, for example, the directory companies Raw materials for the production of varnishes and paints", program supplies, Rohm GmbH Co/KG, Darmstadt, Germany, p.4-5). Antistatic additive is a cationic compound, halogen-free, which is based on the solution of Quaternary ammonium, built-in polymer media, dissolved n-butanol, for example EFKA 6780 (firm "EFKA", the company Degussa, Germany, catalogue of company "EFKA", 2006, str). It is additive to varnishes and paints based on organic solvents to protect the s against static electricity when printing (increases the conductivity of the polymers). The density at the temperature of +25°C - 0,943-0,964 g/cm3. The chemical composition of a cationic chemical compound, halogen-free.

Determination of viscosity by viscometer B3-246 (GOST 9070-75) according to GOST 8420-74 "Materials paint. Method for the determination of viscosity". Determination of adhesion to polyvinyl chloride (method cross-hatch test) were carried out as follows (OST 29.85-88 "Adhesion to neittaanm substrates", item 1.33). Were cut with a razor blade on the sheet in a checkerboard pattern when the distance of the lines of cut of 1 mm from each other (10 lines). Evaluation of production is odiles the peeling paint from the substrate (polyvinyl chloride). Residual stickiness was determined with the help of the device VI-4 to determine the degree of drying of the paint on the glass (OST 29.85-88 "Adhesion to neittaanm substrates", p) after 30 s after application of the spiral rod No. 3 (ink film thickness of 24 μm) in the presence of a trace from the load weight of 200 g on the surface of the imprint after exposure for 1 minute
