The invention relates to a method for depositing an adhesive PVC copolymer layer
on a substrate, characterized in that it comprises the following steps: formation
of a mixture of copolymer precursors in an organic solvent, whereby said mixture
comprises PVC and 0.1-2 wt. % organotrialkoxysilane of formula H(HNR1)xR2Si(OR3)3,
wherein R1 and R2 are alkyl groups or intermediate aromatic
groups, R3 is an aryl group, the three substituents R3 cannot
be the same and x is 0-2; a layer of said mixture is deposited on the substrate;
the mixture is dried in order to evaporate the solvent; the aggregate thus obtained
is heated to a temperature of 70-170 C. for a duration that respectively
ranges from 3 hours and 5 minutes.
