The present disclosure provides an adhesive composition that contains a polyester resin (A), wherein the polyester resin (A) contains a structural unit derived from at least one compound (a1) selected from the group consisting of a dimer acid compound and a dimer diol, and a structural unit derived from an aromatic compound (a2).

An adhesive agent produced by crosslinking an adhesive agent composition containing a polyester resin (i) having a structural portion derived from a polycarboxylic acid compound (a) and a structural portion derived from a polyol component (b), wherein the polyester resin (i) contains a structural portion derived from at least one selected from the group consisting of a dimer acid compound, a sebacic acid compound, and a dimer diol in a proportion of not less than 60 wt. % based on the weight of the polyester resin (i), wherein the polyol component (b) includes a glycol (b1) having an even carbon number (excluding the dimer diol), wherein the polyester resin (i) has an ester group concentration of not less than 2 mmol/g. The adhesive agent has an adhesive force (α) of not less than 1 N/25 mm as measured under predetermined conditions.

There is provided a composition for a laminated material used for a medical lubricating member, the composition including a polymer b1 including a polysiloxane structure and a crosslinkable polymer b2 having a particular reactive group that forms a crosslinked body with the polymer b1 and having a number-average molecular weight of 1000 or more. The crosslinkable polymer b2 is at least one of polysaccharides, polyethyleneimines, polyesters, polyethers, polyamides, polyurethanes, polyureas, or polyimides. There are also provided a laminated material used for a medical lubricating member and including the composition, a medical lubricating member, and a medical device.

The invention relates to isocyanate-based, storage-stable, one-part compositions that are fixable by irradiation with actinic radiation and curable by heat. The composition comprises (A) an at least bifunctional, solid isocyanate having a passivated surface and a melting point of at least 40° C.; (B) an isocyanate-reactive component selected from the group of alcohols, amines and thiols, and mixtures thereof; (C) a radiation-curable compound; and (D) a photoinitiator. Optionally, further additives (E) can be contained in the composition according to the present invention. The compositions, by fixation with actinic radiation, can be transferred into a state that ensures dimensional stability of the compositions during heat curing.

The invention relates to a method for peeling a pressure-sensitive adhesive tape including: a pressure-sensitive adhesive layer. The pressure-sensitive adhesive tape has a thickness greater than 150 μm and smaller than 1,500 μm, an elongation at break of 600% to 3,000%, and a stress at break of 2.5 to 80.0 MPa. According to the invention, the conformity and the adhesion with respect to an adherend, particularly, a hard adherend, are excellent, and excellent re-peeling properties are obtained, so that the pressure-sensitive adhesive tape can be stretched and peeled off in a horizontal direction, without necessity for embrittling the pressure-sensitive adhesive tape by heating or by using an organic solvent or the like or without remaining of the pressure-sensitive adhesive on the adherend, in a case of peeling the pressure-sensitive adhesive tape.
