摘要 |
Heat-curable adhesive composition: (a) a polyurethane composition (A) of formula: in which R1 is a hydrocarbon-based radical; R2 is a polyester block; R3 is a linear C1-C3 alkylene radical; R4 and R5 are a C1-C4 alkyl; m is an integer such that the molar mass of the said polyurethanes is 900-27 000 Da; p=0, 1 or 2; obtained by producing polyester diols by polycondensation of: (i) dimerized fatty acids with an acid number of 190-200 mg KOH/g with a C2-C44 diol optionally having O or S; or (ii) dimerized fatty alcohols with a hydroxyl number of 200-220 mg KOH/g with a C4-C44 dicarboxylic acid optionally having O or S; (b) 22-62% of a compatible tackifying resin (B); and (c) 0.01-3% of a crosslinking catalyst (C). Self-adhesive support obtained by preheating the adhesive composition, coating onto a support layer and then curing. Manufacture of self-adhesive labels and/or tapes. |
