<p>adhesives. SUBSTANCE: invention provides product consisting of (a) effective on short-period pressing glue consisting of copolymer and (b) substrate on which glue is applied. Copolymer (a) contains approximately, weight parts: (i) at least one monomer selected from group including first multifunctional acrylate or methacrylate ester of non-tertiary ca. C4-C12-alkanols having, in the form of homopolymer, vitrification temperature below -25 C, 50 to 90; (ii) polymerizable N,N-dialkyl-substituted amides, 10 to 25; (iii) acid monomer capable of polymerization with monomers (i) and polymerizable amides (ii), the latter being present at molar excess, 5 to 7; (iv) second multifunctional acrylate or methacrylate ester of non-tertiary alcohols having, in the form of homopolymer, vitrification temperature equal to or higher than -25 C, 0 to 30; and (v) cross-linking agent in amounts from 0.01 to 1% based on total weight of (i)+(ii)+(iii)+(iv). Proportions of components are selected such as to make product capable of standing at least three tests from the following ones: washing away with water under pressure after impregnation with water, washing away with water under pressure after temperature-control period, initial static shear test, static shear test after temperature-control period, initial T- peeling test, T-peeling test after thermal conditioning, and T-peeling test after impregnation with water. Invention also covers glues ensuring reliable gluing of light-reflecting and non-light-reflecting substrates with surfaces such as polyvinylchloride-coated cloth. EFFECT: increased gluing reliability. 18 cl, 3 dwg, 2 tbl, 9 ex</p> |
