ADHESIVE COMPOSITION, ADHESIVE FOR ELECTRONIC COMPONENT, AND ADHESIVE FOR DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/130043
Kind Code:
A1
Abstract:
The adhesive composition according to the present invention comprises a radical polymerizable compound and a photoradical polymerization initiator and satisfies requirements (1) and (2) [wherein: Tga stands for the tanδ peak temperature in the dynamic viscoelasticity measurement of a cured product that is prepared by curing the adhesive composition in the presence of oxygen; and Tgb stands for the tanδ peak temperature in the dynamic viscoelasticity measurement of a cured product that is prepared by curing the adhesive composition in the absence of oxygen]. Requirement (1) |Tgb-Tga|≤30°C, Requirement (2) -15°C≤Tga≤35°C According to the present invention, an adhesive composition having high initial bond strength and good shape retention properties can be provided.
