The present invention aims to provide an adhesive tape having excellent adhesion and exhibiting excellent holding power even under prolonged shear stress at high temperature. Provided is an adhesive tape including an adhesive layer, the adhesive layer containing an acrylic copolymer containing a structural unit derived from an alkyl (meth)acrylate and a structural unit derived from an olefin polymer having a polymerizable unsaturated double bond at an end, the adhesive layer having a swelling ratio of 40 or greater and 500 or less when immersed in tetrahydrofuran at a temperature of 25 C. for 24 hours.

The invention provides a method for preparing a binder precursor, the method comprising the steps of: i) mixing (A) fungi or glucan and (B) starch with an alkaline agent in the presence of an aqueous solvent system to form an alkaline composition; ii) mixing the alkaline composition with an acidic agent to form a mixture; and iii) drying the mixture and forming a powder therefrom, so as to form a powdered binder precursor.

There is provided an aqueous adhesive composition for forming an adhesive layer of a fabric transport member of an ink jet textile printing apparatus including a transport mechanism that bonds a fabric to the adhesive layer formed at a surface of the fabric transport member to transport the fabric, a heating portion that heats the adhesive layer, a bonding portion that bonds the fabric to the heated adhesive layer, a recording portion that attaches an ink composition to the fabric bonded to the adhesive layer using an ink jet head, a peeling portion that peels off the recorded fabric from the adhesive layer, and a cleaning portion that cleans the adhesive layer from which the fabric is peeled off with a cleaning solution containing water, the aqueous adhesive composition including: a (meth)acrylic resin; and water, in which when an adhesive force with which the fabric is peeled off from the adhesive layer cooled to 23 C. after bonding the fabric to the adhesive layer heated to 33 C. is represented by an adhesive force A (N/50 mm) and an adhesive force with which the fabric is peeled off from the adhesive layer at 23 C. after bonding the fabric to the adhesive layer at 23 C. is represented by an adhesive force B (N/50 mm), a change rate of adhesive force per unit temperature represented by (AB)/(33 C.23 C.) is 0.050 N/ C..Math.50 mm or more.

Disclosed are an adhesive film which may be applied to not only rigid electronic devices but also soft electronic devices by having excellent mechanical strength and adhesive strength due to hydrogen bonding and galloyl interaction, as well as high transparency, coating uniformity, and flexibility, an adhesive member including the same, and a bonding method using the same.

A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.
