摘要： A water-developable plate package comprising water-developable plates packaged in a laminated state. The water developable plate is a sheet-like plate comprising a photosensitive layer made of a photosensitive resin composition having water-developability and a protective film covering both surfaces of this photosensitive layer. The package prevents the occurrence of deformation of the plates in a packaged state during transportation or storage at a high temperature and a high humidity in summer without complicating the operations at the time of use or packaging of plates and without increasing the cost remarkably. The package is obtained by sandwiching an open-cell foam sheet (2) between the water-developable plates (1 and 1) to form a laminate (3), wrapping the laminate (3) with a light-screening film and fixing the wrapping ends with a tape. Because the foam sheet (2) exists, in-plane non-uniformity of hygroscopicity of the plates (1) can be corrected during transportation or storage at a high temperature and high humidity in summer, and the deformation of the plates (1) can be restricted.

摘要： A production method for a branched conjugated diene-based polymer, comprising:
a polymerizing step of obtaining a conjugated diene-based polymer having an active end by polymerizing or copolymerizing a conjugated diene compound, or a conjugated diene compound and an aromatic vinyl compound with an alkali metal compound or an alkaline earth metal compound used as a polymerization initiator; and
a branching step of introducing a branch structure by reacting a styrene derivative as a branching agent with the active end of the conjugated diene-based polymer.
