ABSTRACT:
Disclosed is an easy to use optical adhesive composition which has lower refractive index than the conventional optical adhesive compositions while having low viscosity, fast curability and excellent heat resistance. Also disclosed are a method for bonding an optical component using such an optical adhesive composition which enables to reduce transmission loss, and an optical device. Specifically disclosed are an optical adhesive composition characterized by comprising at least one acrylate compound represented by the general formula (I) and a photopolymerization initiator, a method for bonding an optical component using such an optical adhesive composition, and an optical device. Tf-(O)a—(CH2)b—(CF2)m—(CH2)b—(O)a-Tf (I) wherein a's are the same represent 0 or 1, b's are the same represent 0 or 1, m represents an integer of 4 to 12, and Tf's are the same and represent a glycidyl group or CH2═CH—C(O)—.
