再剥離性粘着剤組成物、その製造方法及び該再剥離性粘着剤組成物を用いた再剥離性粘着体
Document Type and Number:
Japanese Patent JP4334643
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a re-releasable adhesive composition which has a high adhesion property, is suitably used in tapes, labels, sheet, surface-protection films, etc., and stably exerts a sufficient sticking ability and releasability against an adherend, even when sticking and releasing are repeated under various environments. SOLUTION: A re-releasable adhesive composition comprises as a main agent a synthetic resin emulsion containing an adhesive acrylic polymer particle wherein the surface part (shell) and the inner part (core) are crosslinked. Preferably, the synthetic resin emulsion is in a state achieved by using a hydrophilic crosslinking agent in combination with a lipophilic crosslinking agent, a state wherein the hydrophilic crosslinking agent is a monomer having a silyl group and the lipophilic crosslinking agent is a monomer having two or more radical polymerizable unsaturated bonds, a state wherein the hydrophilic crosslinking agent is a polymerizable surfactant having two or more radical polymerizable unsaturated bonds and the lipophilic crosslinking agent is a monomer having a silyl group, etc.
