GLUE COMPOSITION OF LABELING ASSIGNMENT Russian patent published in 2006 - IPC C09J103/02 

FIELD: production of the glue composition of labeling assignment.

SUBSTANCE: the invention is pertaining to production of the glue composition of labeling, in particular, to the glue composition designated for sticking of the glue impregnated-paper labels to the glass, plastic, metallic, ceramic and wood surfaces. The invention allows to produce the glue compositions, which are distinguished by the increased frost-resistance: withstanding the multiple freezing and defreezing. The composition is produced by combination of two compounds preliminary heat-treated at the temperature of 80-90°C and their subsequent heat treatment together with the modifying agent - Amylum at 90-95°C, and bring up to pH=7.0-7.5 IN by KOH or NaOH solution. At that the composition 1 contains: dextrin, gum-arabic pretreated at 130°C and under the residual pressure of 05 mmHg, water; the composition 2 contains: colophony, glycerin, borax, water. At that the first composition was thermotreated in presence of several drips of antifoaming liquid. The labels gain positive stability against a shearing within 10 seconds and after 5 minutes can be torn-off only with a break of the paper.

EFFECT: the invention ensures, that the labels gain positive stability against a shearing within 10 seconds and after 5 minutes can be torn-off only with a break of the paper.
