Abstract
A cohesive coating composition comprises in dispersion in a liquid a mixture of between 51 and 99% by weight of a natural or synthetic rubber and between 1 and 49% by weight of polyalkyl methacrylate in which dispersion there is incorporated between 5% and 35% by weight, based on the weight of the solids, of a inert particulate material having a mean particle size lying in the range between 0.2 and 50 microns. The compositions are applied to sheet materials used, for example, in packaging.
