SELF-ADHESIVE MASS FOR ADHESIVE FLEXIBLE PRINTING PLATES Russian patent published in 2018 - IPC C09J133/00 C09J133/26 C09J7/00 B32B37/12 B41N6/02 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a self-adhesive mass, to a method for its preparation and its application for gluing printing plates. Self-adhesive mass includes at least 60 wt. % the polymer mixture, and the polymer mixture consists of the first polymer component A, the second polymer component B and, if necessary, one or more additional polymer components C. First polymer component A is present in the polymer mixture in an amount of at least x wt. %, with 90 ≤ x ≤ 99. Second polymer component B and, if necessary, an additional polymer component C is present in the polymer mixture in a total amount of y wt. %, and y = 100 – x. Each polymer component (A, B, C) is formed of (meth) acrylic monomers by at least 60 % by weight. None of the polymer components (A, B, C) at room temperature is not homogeneously miscible with one of the other polymer components (A, B, C).

EFFECT: difference Z of the Hansen solubility parameters of each of the indicated polymer components relative to each of the other polymer components takes the value of more than 1, so that a multiphase system is present.
