    • An adhesive resin composition is described, comprising: (A) a thermoplastic copolyester resin prepared from (1) a dicarboxylic acid component comprising from 40 to 100 mol % of terephthalic acid and from 0 to 60 mol % of other aromatic dicarboxylic acid and (2) a low molecular weight glycol component comprising from 40 to 100 mol % of 1,4-butanediol and from 0 to 60 mol % of diethylene glycol or 1,6-hexanediol and further from 0 to 10 mol %, based on the total carboxylic acid, of polytetramethylene glycol having a molecular weight of from 600 to 6,000, which has a melting point of from 90.degree. to 160.degree. C. and a reduced viscosity of at least 0.5; and (B) an ethylene copolymer having at least one functional group selected from an epoxy group, a carboxylic acid group, and a dicarboxylic anhydride gruop; and if desired, (C) a thermoplastic resin other than the resin (A), and if further desired, (D) a polyfunctional epoxy compound. This composition exhibits excellent adhesion to synthetic resins such as polyvinyl chloride, polyesters, and polyolefins and also to metals such as aluminum and has excellent adhesive durability against moisture.
    • 描述了一种粘合剂树脂组合物,其包括:(A)由(1)包含40-100mol%对苯二甲酸和0-60mol%其它芳族二羧酸的二羧酸组分制备的热塑性共聚酯树脂和(2) )低分子量二醇组分,其包含40至100摩尔%的1,4-丁二醇和0至60摩尔%的二甘醇或1,6-己二醇,进一步为0至10摩尔%,基于总羧酸 酸,分子量为600〜6000的聚四亚甲基二醇,其熔点为90〜160℃,比浓粘度为0.5以上; 和(B)具有至少一个选自环氧基,羧酸基和二羧酸酐基团的官能团的乙烯共聚物; 如果需要,(C)除了树脂(A)以外的热塑性树脂,如果需要,(D)多官能环氧化合物。 该组合物对聚氯乙烯,聚酯和聚烯烃等合成树脂以及铝等金属表现出优异的粘附性,并且对水分具有优异的粘合耐久性。
