FIELD: adhesives. SUBSTANCE: pressure-sensitive glue composition contains water-emulsion latex system prepared from polymer of at least one ethylenically-unsaturated monomer, hard or soft, which polymer is effective for stabilizing latex system of water-soluble protective colloid with number-average molecular weight below ca. 75000, amount of soft monomer in latex polymer being superior to that of hard monomer and ratio of hard monomers to soft ones in latex polymer being chosen such as to provide, at operating temperature selected, formation of continuous latex film with nitrification temperature from ca. -100 C to ca. -3 C and value of 1 kg shear resistance on steel higher than 2000 min in absence of surfactant. EFFECT: improved physico-mechanical characteristics of latex films. 24 cl, 8 tbl, 18 ex |
