Title:
COMPOSITION FOR TEMPORARY FIXING OF THIN LAYER GLASS, AND METHOD FOR PROCESSING THIN LAYER GLASS
Document Type and Number:
WIPO Patent Application WO/2022/255382
Kind Code:
A1
Abstract:
The present invention provides a single component composition for temporary fixing of thin layer glass. The composition exhibits excellent photocuring properties and enables thin layer glasses to be strongly temporarily fixed to each other while enabling the thin layer glasses to be easily peeled from each other in a short time at the time of peeling. This composition for temporary fixing of thin layer glass contains a monofunctional acrylic monomer, a polyfunctional monomer, thermally expandable fine particles and a radical photopolymerization initiator having a molar absorption coefficient ε of 100 L/(mol·cm) or more at a wavelength of 400 nm, exhibits excellent photocuring properties, and enables thin layer glasses to be temporarily fixed to each other regardless of stress at the time of processing while enabling the thin layer glasses to be easily peeled from each other in a short time with no damage following processing of the thin layer glasses.
