Title:
SELF-ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP3807777
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a self-adhesive sheet having a self-adhesive layer containing a hydrophilic group-having monomer as the copolymerization component of a self-adhesive copolymer, exhibiting excellent self-adhesivity, even an AS agent is coated on the surface of an adherend, and useful for the lid sheets of magazines for packing electronic parts, etc.
SOLUTION: A monomer containing a hydrophilic group (preferably either one of hydroxyl group, carboxyl group, amino group, amide group and imide group) is copolymerized in an amount of 5-55mol.% as the copolymerization component of a self-adhesive copolymer constituting a self-adhesive layer. A powdery filler having an average particle diameter smaller than the thickness of the self-adhesive layer and/or a fibrous filler having an average diameter smaller than the thickness of the self-adhesive layer is preferably added to the self-adhesive layer in an amount of 2-40wt.% based on the solid content of the self-adhesive agent.
