In a decorative sheet including a surface layer and an adhesion layer, the surface layer is a polyurethane layer obtained by crosslinking using a curing agent and coating and drying of a straight chain polyurethane resin having a specified molecular weight and acid value, the polyurethane resin being obtained by reaction of a diamine chain extender agent with a polyurethane prepolymer obtained by reaction of a polycarbonate diol having an alicyclic structure, an aliphatic diol having a carboxyl group, and 4,4-cyclohexylmethandiisocyanate.

A building material comprising a substrate layer and a pressure-sensitive adhesive layer, where the pressure-sensitive adhesive layer includes expandable graphite.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

The present invention provides a mask adhesive that plastically deforms easily, no adhesive residue remains after peeling from the mask, ease of handling is excellent, and haze on a pellicle film is unlikely to be increased. A mask adhesive resolving this problem contains a thermoplastic elastomer (A) for which the temperature at which the loss tangent measured at a frequency of 1 Hz is at a maximum value is 20 to 30 C., a tackifier resin (B), and a process oil (C). The total of the proportion (% CP) of paraffin carbon and the proportion (% CN) of naphthene carbon in the process oil (C) is 50% or more. The temperature of the mask adhesive at which the loss tangent measured at a frequency of 1 Hz is at a maximum value is 10 to 30 C., and the sulfur content of the mask adhesive is 300 g/g or less.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.

Provided herein is a hot melt pressure sensitive adhesive comprising one or more styrene block copolymers, a tackifier, and polyisobutylene plasticizer, wherein the adhesive contains less than 1 wt % of a plasticizer oil. The adhesive can be used in a label construction along with a facestock such as a polyethylene facestock, wherein the swelling factor of the facestock is reduced as compared to the swelling factor of the facestock in labels that include a plasticizer oil. Also provided are methods for producing and using the hot melt adhesive, and articles labeled with the hot melt adhesive.
