Title:
可塑剤及び光学用粘接着剤組成物
Document Type and Number:
Japanese Patent JP6730674
Kind Code:
B2
Abstract:
The present invention relates to a plasticizer and an adhesive composition for optical use, and aims to provide the plasticizer which has long-term heat resistance and excellent initial tone and compatibility without inhibiting polymerization of a monomer of a thermosetting and/or active energy ray-curable resin and which can be suitably used for an adhesive composition for optical use. The plasticizer comprises a rosin ester. The rosin ester is a reaction product of rosin and a monohydric alcohol having 1 to 9 carbon atoms and has a Gardner color scale of 1 or less, a glass transition temperature of -15 DEG C or lower, and an esterification degree of 94 wt.% or more, in which a content of an abietic acid type resin acid having a conjugate double bond and no aromatic ring and its ester is less than 10 wt.%.
