| 摘要 |
<p>The invention concerns a multilayer composite product comprising at least once successively a first soft or rigid material layer; a second layer consisting of a pressure-sensitive adhesive polymeric film formed by applying on the first layer at least a latex (L1), then by drying said latex; and a third layer consisting of a soft or rigid material, a latex (L1) obtained by emulsion polymerisation of the mixture of the following monomers, for 100 wt. %: 40-95 wt. % of at least a (meth)acrylic or vinyl monomer capable of resulting in a homopolymer having a Tg ≤ -40 °C; 2-50 wt. % of at least a (meth)acrylic or vinyl monomer capable of resulting in a homopolymer having a Tg ≥ 0 °C; 1-6 wt. % of at least a (meth)acrylic carboxylic monomer; 0.5 wt. % of at least (meth)acrylic monomer ethoxylated with 1-20 ethylene oxide moles; more than 0.075 wt. % to 5 wt. % of at least a (meth)acrylic or vinyl monomer comprising a ureido group; and 0-2 wt. % of at least an acrylic or vinyl monomer bearing a sulphonate function.</p> |
