摘要： An elastic laminate sheet comprising a laminate comprising an elastomer layer and a nonwoven fabric provided on at least one surface of the elastomer layer, wherein low elastic laminate part and high elastic laminate part are alternatingly provided in one direction to form the laminate, and the low elastic laminate part and the high elastic laminate part both have a first bonding region where the elastomer layer and the nonwoven fabric are bonded and a second bonding region where the elastomer and the nonwoven fabric are bonded more weakly than at the first bonding region, and a total surface area of the first bonding region in the low elastic laminate part is larger than a total surface area of the first bonding region in the high elastic laminate part, and a ratio of an elastic modulus of the low elastic laminate part to an elastic modulus of the high elastic laminate part is more than 1 and not more than 7.5. The elastic laminate sheet does not easily break even when repeatedly stretched and demonstrates sufficient retention capacity for practical use even when attached to a main body part of a hygienic article or the like.

摘要： An elastic multilayer body is provided with excellent elastic characteristics, film durability, and productivity. The elastic multilayer body includes a nonwoven material and a layer that includes an elastomer composition. The elastomer composition includes (a) polyurethane elastomer, (b) styrene-isoprene-styrene copolymer, and (c) 0 mass% or more and less than 4 mass% of a tackifier based on the amount of the elastomer composition. The amount of the component (a) is between 90 and 99.9 mass% based on the total amount of components (a) and (b). The amount of the component (b) is between 0.1 and 10 mass% based on the total amount of components (a) and (b).
