A breathable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch.sup.2 to about 4600 per inch.sup.2, said pores being uniformly distributed to form a flow path through the adhesive.

A composite polyester hot-melt adhesive, a preparation method thereof and a preparation method of an anti-scouring geotextile are provided. The preparation method of the composite polyester hot-melt adhesive includes the following steps: performing an esterification reaction on a dibasic acid and a dihydric alcohol under a protection of nitrogen and an action of a titanium/cobalt composite catalyst, adding a stabilizer for a polycondensation reaction to obtain a polyester hot-melt adhesive, then adding polymethyl methacrylate (PMMA) microspheres for mixing and stirring to obtain the composite polyester hot-melt adhesive. The anti-scouring geotextile is obtained by bonding a polyethylene terephthalate woven fabric with a polypropylene geotextile by the composite polyester hot-melt adhesive. The composite polyester hot-melt adhesive has the advantages of high bonding strength and good anti-impact performance, and the prepared anti-scouring geotextile has the advantages of high anti-scouring strength, good soil conservation performance, strong protection capability and long service life.

Provided is a novel pressure-sensitive adhesive sheet that is capable of having good light-blocking properties while having an increased refractive index. The pressure-sensitive adhesive sheet provided by the present invention has a pressure-sensitive adhesive layer comprising a black colorant. The pressure-sensitive adhesive sheet has a refractive index of 1.50 or higher.

The present disclosure discloses a support film, an OLED display structure and a manufacturing method thereof The support film includes a first adhesive material layer and a first base material layer, which are stacked together, and a first release film therebetween.

The present invention discloses an ultra-quiet backing-paper-free cold laminating film comprising a substrate layer, a release layer, and an adhesive layer, the release layer and the adhesive layer being each attached to a respective side of the substrate layer, the release layer being obtained by drying a release agent applied on the substrate layer, and the release agent consisting of the following components by weight: 2-ethylhexyl acrylate, vinyltrimethoxysilane, 1-methyl-1-phenylethyl hydroperoxide, vinyl-terminated silicone resin, di-t-butyl cumene peroxide, fluorosiloxane, ethyl acetate, ethylene glycol dimethyl ether, a toughening agent, polysiloxane-polyether copolymer, silicone and wax powder. In the invention, the peel strength is reduced; it is ensured that the release force of the cold laminating film is not affected by the external environment, such that the cold laminating film has good stability; and meanwhile the subsequent adhesion of the release layer is improved, so that it can ensure that the adhesive force of the adhesive layer would not be affected after long-term adhesion between the adhesive layer and the release layer.

A method of preparing self-adhesive polyester elastomer composite membrane includes the following steps: mix methyl formate or ethyl acetate with thermoplastic polyester elastomer (TPEE) powder or granules; add a modifier, a photo initiator or a thermal initiator; continue mixing to prepare uniformed mixture; after drying uniformed mixture prepare a polyester elastomer membrane through an injection laminating process and apply pressure sensitive adhesive on one side of the polyester elastomer membrane. Prepared membrane poses good bonding characteristics to textile materials and can be used in production of clothing.

The invention relates to a peel detection label that is a laminate including a support, a pattern layer formed in a part of the surface of the support, and a pressure-sensitive adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order, in which the low modulus layer (X) has an n-layered structure (where n is an integer of 1 to 10) having a surface in contact with the support and the pattern layer and a surface in contact with the high modulus layer (Y), and the low modulus layer (X) satisfies a specific thickness-average shear storage elastic modulus.

##STR00001##

wherein n is an integer with a value of 2 or 3, R.sup.1 is a linear, cyclic or branched alkyl residue that optionally contains ether oxygen atoms and R.sup.2 is a methyl or ethyl group; between 10 and 30 wt.-% of at least one Lewis base having at least one tertiary amino group, amidine group, or guanidine group; and between 10 and 30 wt.-% of at least one carboxylic acid.

The present invention is stickers for exercise mats, such as those commonly used in yoga or pilates. These mat stickers are available in a multitude of geometric shapes and adhere to the mats via an acrylic surface. A preferred thickness for the mat stickers is approximately 1.5 mm, which provides a sufficient grip for the practitioner, but is thin enough to roll into the mat at the conclusion of the exercise.
