An adhesive containing at least one selected from the group consisting of a urethane prepolymer and a polyol, a polyisocyanate, a polymerizable (meth)acrylate compound, and a photopolymerization initiator is disclosed. A heat-sensitive screen master and a method for producing a heat-sensitive screen master are also disclosed.

An adhesive for a heat-sensitive screen master is disclosed, the adhesive containing at least one selected from the group consisting of a urethane prepolymer and a polyol, and a polyisocyanate, wherein the mass ratio (A:B) between the at least one (A) selected from the group consisting of a urethane prepolymer and a polyol, and the polyisocyanate (B) is within a range from 35:65 to 5:95. A heat-sensitive screen master and a method for producing a heat-sensitive screen master are also disclosed.

A structure of a screen printing plate comprises a supporting frame, a composite screen, a first and a second adhesive body, and an adhesive tape. The composite screen is connected to the supporting frame and comprises a first and a second screen. The first screen is disposed along the supporting frame and encloses a central region. The second screen covers the central region and is in partial overlapped with and connected to the first screen, wherein the screens are made from different materials. The first adhesive body is disposed between the first and the second screens and connects them. The second adhesive body is disposed on one side of the composite screen and covers the first adhesive body. The adhesive tape is opposite to the second adhesive body and is disposed on the other side of the composite screen. A manufacturing method of a screen printing plate is also provided.
