PURPOSE:To obtain adhesive which can keep adhesiveness and can be cured under a relatively low temperature and has sufficient heat-resistance properties and reliability by a method wherein a specific compound which has at least two maleimide groups is dispersed with a specific ratio in solution which is obtained by dissolving specific butadiene-acrylonitrile copolymer in organic solvent. CONSTITUTION:Butadiene-acrylonitrile copolymer which is expressed by a formula I or a formula II, contains piperazinylethylaminocarbonyl group has a weight- average molecular weight of 1000-200000, contains 5-50wt.% acrylonitrile and has an amino group equivalent of 500-10000 is dissolved to obtain solution (a). A compound (b) which contains at least two maleimide groups and is selected among compounds expressed by formulae III-VI is dispersed in the solution (a) so as to have 10-900wt. parts of the component (b) for 100wt. parts of the component (a). In the formula I and formula II, (k), (m) and (n) denote in mole ratios and, when n=1, (k) and (m) are in ranges that k=3-175 and m=0.3-93. |
