The present invention relates to an adhesive tape having a layer structure in which an adhesive layer, a first film layer (I), a base material layer, and a second film layer (II) are arranged in this order, in which the base material layer satisfies a predetermined requirement that a ratio (a)/(b) of a thickness (a) to a thickness (b) is not less than 1.7 or not more than 0.6 in which the thickness (a) is a thickness from the first film layer (I)-side of the base material layer to the outer surface of the adhesive layer and the thickness (b) is a thickness from the second film layer (II)-side surface of the base material layer to the outer surface of the second film layer (II), and at least one layer constituting the layer structure contains a flame retardant (C).

Disclosed are a hot melt tape for hook-and-loop fasteners without sewing which may be adhered at a low temperature and complete hardening of an adhesive resin in a short time and a method for manufacturing a seat padding material for vehicles using the same. The method includes preparing the padding material and a hook-and-loop fabric, preparing a hot melt tape having a hot melt resin layer by coating a surface of a release paper with a reactive hot melt resin having a melting point of 40-80° C. before reacting, adhering the hot melt tape to a surface of the padding material by applying heat of a temperature of 30-70° C. and pressure thereto, removing the release paper, adhering the hook-and-loop fabric to the exposed hot melt resin layer, and hardening the hot melt resin layer by cooling the padding material and the hook-and-loop fabric to a temperature of 0-20° C.

An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.
