AQUEOUS ADHESIVE COMPOSITION Russian patent published in 2018 - IPC C09J133/08 C09J4/06 

FIELD: chemistry.

SUBSTANCE: invention relates to an adhesive (meth)acrylate-based composition, which is used as an adhesive for labeling or sealing adhesive. Composition is an aqueous (meth)acrylate dispersion, which contains, based on the total weight of the adhesive composition: (a) 15.0–55.0 wt% of a polymer based on (meth)acrylate monomers, containing at least a copolymerisable auxiliary monomer selected from the group consisting of ethylenically unsaturated mono- and dicarboxylic acids, and (b) 0.1–5.0 wt% stabiliser. Stabiliser is a copolymer based on at least one vinyl ester, preferably vinyl acetate, and at least one diester of an alkene of formula H₂C=CHR¹-(CHR²)n-CH₂R³, where at least two of R¹, R² and R³ are -OC(O)R⁴, and the rest denote hydrogen, R⁴ is C_1-6-alkyl, preferably methyl, and n is 0, 1, 2, 3, 4 or 5, and the copolymer is partially or fully hydrolysed.

EFFECT: obtaining an adhesive composition that provides good adhesion on cold and wet surfaces.
