    摘要: A tacky resin composition which has proper initial tackiness, is sufficiently inhibited from rising in tackiness with time, can keep tackiness at a proper range even when it receives a slight heat history or is stored for a long time, has very small dependence on peeling speed, and can provide high transparency to a pressure-sensitive adhesive film or sheet as required, and a pressure-sensitive adhesive film or sheet for the surface protection of an article, which is obtained form the tacky resin composition. The tacky resin composition comprises (A) 5 to 80 parts by weight of an olefin polymer (component A), (B) 5 to 80 parts by weight of an ethylene/unsaturated ester copolymer (component B) and (C) 1 to 60 parts by weight of a styrene-based elastomer and/or an olefin-based elastomer (component C) based on 100 parts by weight of the total of the components A, B and C.

    摘要: A hot melt adhesive comprises an ethylene α-olefin copolymer, an acid anhydride modified polyolefin and a hydrogenated tackifying resin. The hot melt adhesive has excellent viscoelastic properties and can be used in a variety of applications. In one application, attaching an elastic band to a flexible film, the adhesive has excellent viscosity and, in a finished absorbent article, a minimal creep characteristic. Also disclosed is a disposable article using the adhesive to adhere adjacent surfaces within the disposable article including an elastic band to a polyolefin backing film, for example, in a diaper, incontinent article or other such structure.
