Title:
LAMINATE, DEVELOPING MEMBER, AND LAMINATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/135284
Kind Code:
A1
Abstract:
The present invention provides a laminate exhibiting excellent elasticity and improved adhesion between layers. The present invention further provides a developing member exhibiting excellent elasticity and improved adhesion between layers. Moreover, the present invention provides a laminate manufacturing method enabling the manufacture of a laminate exhibiting excellent elasticity and improved adhesion between layers. This laminate comprises at least a base layer, an intermediate layer formed on the base layer, and a surface layer formed on the intermediate layer, and is characterized in that: the base layer is formed by polymerizing a base layer composition comprising at least a compound A having a (meth)acryloyl group in the molecules thereof; the intermediate layer is formed by polymerizing an intermediate layer composition comprising (i) a compound B having at least two functional groups in the molecules thereof, at least one of said functional groups being a (meth)acryloyl group, and (ii) a compound C having at least two functional groups in the molecules thereof, at least one of said functional groups being a hydroxyl group; the surface layer is formed by polymerizing a surface layer composition comprising at least a compound D having an isocyanate group in the molecules thereof; and the (meth)acryloyl groups in the base layer bond with the (meth)acryloyl groups in the intermediate layer composition, and the hydroxyl groups in the intermediate layer bond with the isocyanate groups in the surface layer composition.
