PROCESS FOR PREPARING WATER-DISPERSIVE ADHESIVE FOR FIXING POLYMERIC FILMS TO PRINTED MATTER Russian patent published in 1996 - IPC

FIELD: chemical industry. SUBSTANCE: water-dispersive adhesive for fixing polymeric films is prepared by mixing latex of carboxyl-containing butadiene-methyl methacrylate copolymer obtained by water emulsion copolymerization of 60-80 wt parts of butadiene-1,3 with 20-40 wt parts of methyl methacrylate and 0.1-3 wt part of methacrylic acid in the presence of 0.4-1 wt part of tertiary dodecyl mercaptan as molecular weight regulator followed by concentration to concentration of 40-50 wt%, and latex CKC-65 which is latex of butadiene-1,3-styrene copolymer. Latexes are mixed in weight ratio of (0.8-1.2): (1.2-0.8) respectively calculated as dry matter and the mixture is adjusted to conventional viscosity of 20-55 and thickening agent is added. EFFECT: improved properties of the adhesive. 1 tbl
