Abstract
The invention relates to a paper composite material with repulp-resistant adhesive coating, consisting of a paper carrier and an adhesive layer, characterized in that an intermediate coat of a dispersion polymer film containing a protective colloid and/or an emulsifying agent and with a glass transition temperature Tg of −20° to 40° is applied between the paper carrier and the adhesive coating. The invention also relates to a method for the production of paper composite material with repulp-resistant adhesive coating.
