<p>PURPOSE:To obtain the titled vehicle, by blending a polyamide resin prepared by subjecting a polyalkylenepolyamine, polyol and polymerized fatty acid to condensation reaction with an alkyl titanate based chelating agent and having improved heat as well as rubbing resistance. CONSTITUTION:A vehicle obtained by blending (A) a polyamide resin prepared by subjecting (i) a polyalkylenepolyamine expressed by the formula H2N (RNH)nH (R is 2-3C alkylene, n is 1-5), e.g. ethylenediamine, etc., (ii) a polyol having 2-4 OH groups in one molecule and 48-250 molecular weight, e.g. ethylene glycol, etc., and (iii) a polymerized fatty acid to condensation reaction with (B) an alkyl titanate based chelating agent, e.g. tetraisopropyl titanate, etc. The composition of the component (iii) contains preferably 0-5wt% 18C monobasic acid, 60-100wt% 36C dibasic acid and 0-30wt% 54C tri- or polybasic acid.</p> |
