Title:
CURABLE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/190158
Kind Code:
A1
Abstract:
Curable resin compositions wherein a polyfunctional thiol compound and a specific thioether-containing alkoxysilane derivative are mixed with an epoxy resin composition and a polyfunctional polyene that has a plurality of double bonds have excellent adhesion to inorganic substrates and, as resin compositions, have excellent storage stability. However, cured films of such compositions have poor flexibility in cold places and, as a result, crack easily when bent. Said cured films also have poor adhesion. The present invention provides a material that has excellent adhesion to substrates, even in cold places, and that can produce a flexible cured film. A curable resin composition that contains (A) a thioether-containing (meth)acrylate derivative that has a specific structure and (B) a polyfunctional (meth)acrylate that has a weight average molecular weight of 200-50,000. The mass ratio ((A)/(B)) of the (A) component and the (B) component is 0.05-30.
