ULTRAVIOLET-CURABLE PRESSURE-SENSITIVE ADHESIVE COMPOSITION

Title:

ULTRAVIOLET-CURABLE PRESSURE-SENSITIVE ADHESIVE COMPOSITION

Document Type and Number:

Japanese Patent JP3634875

Kind Code:

B2

Abstract:

PURPOSE: To obtain the title composition which brings about only a slight decrease in bonding strength to a bonded object even in long-term standing at a high temp. by using specific (meth)acrylic esters, a specific oligoacrylate, and a photopolymerization initiator.
CONSTITUTION: This adhesive composition comprises 100 pts.wt. (meth)acrylic ester of a 4-14C alkyl alcohol (e.g. 2-ethylhexyl acrylate), 51-5 pts.wt. alkylphenoxypolyalkylene glycol (meth)acrylate (e.g. nonylphenoxydipropylene glycol acrylate), a polyfunctional oligoacrylate having a mol.wt. of 300 or higher (e.g. hydroxypivalic acid neopentyl glycol diacrylate), and a photopolymerization initiator (e.g. 2-hydroxy-2-methyl-1-phenylpropan-1-one).
