Laminates, their production and use
First Claim
1. An embossable laminate comprising a) a sheetlike substrate having at least one absorbent surface, b) a film and c) an adhesives;
- wherein the film is joined to the substrate by means of said adhesive which comprises a polymer dispersion prepared by free-radical emulsion polymerization and an organosilane comprising at least one silane group and at least one primar, secondary or tertiary amino group, at least one epoxide group, or at least one ethvlenically unsaturated group and one silane group, and wherein the organosilane is incorporated into the polymer during the polymerization or is added subsequently.

Abstract
A description is given of laminates comprising sheetlike substrate and film joined to the substrate by means of an adhesive which comprises a polymer dispersion prepared by free-radical emulsion polymerization and an organosilane which is incorporated into the polymer during the polymerization and/or is added subsequently and which in addition to at least one silane group has at least one primary, secondary or tertiary amino group or at least one epoxide group or which comprises at least one ethylenically unsaturated group and at least one silane group. Through the addition of an organosilane it is possible to produce laminates which can be processed rapidly and which are distinguished by improved embossing strength.
