PRESSURE-SENSITIVE FILM AND METHOD OF MAKING SAID FILM Russian patent published in 2010 - IPC C09J153/00 C09J7/00 C09J7/02 C08F220/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a pressure-sensitive film suitable for protecting car bodies and method of making said film. The pressure-sensitive film is made by depositing onto a carrier film a mixture consisting of an acrylic dispersion; a joint formation system which is in aqueous phase and anti-ageing agents. The carrier film is made from polyethylene and additionally contains one or more polyolefins. The deposition step is carried out under conditions which facilitate formation of an adhesive layer with thickness ranging from 5 to 30 micrometres, and residual moisture ranging from 0.001 to 1 wt %. The process of depositing the mixture involves drying at temperature ranging from 50 to 95°C for 1 to 30 seconds.

EFFECT: film has high level of adhesion, does not contain solvents, is not prone to losing adhesiveness prematurely under the effect of natural conditions.
