PHOTOCURABLE RESIN COMPOSITION AND METHOD OF MANUFACTURING IMAGE DISPLAY DEVICE USING THE SAME

摘要

A photocurable resin composition contains an acrylate-based oligomer component as component (a), an acrylic-based monomer component as component (b), a plasticizer component as component (c), and a photopolymerization initiator component as component (d). The total amount of the component (a) and the component (b) contained in the photocurable resin composition is 25 to 80% by mass, and the amount of the plasticizer component as the component (c) contained in the photocurable resin composition is 65 to 10% by mass. The component (c) contains a solid tackifier and a liquid plasticizing component, and the mass ratio of the tackifier to the liquid plasticizing component is in the range of 60 to 30:30 to 10.

1. A photocurable resin composition that can be used to manufacture an image display device including an image display member and a light-transmitting cover member that are stacked through a light-transmitting cured resin layer formed from the photocurable resin composition in a liquid form, the photocurable resin composition comprising the following components (a) to (d):
an acrylate-based oligomer component selected from the group consisting of a polyisoprene-based (meth)acrylate oligomer, a polybutadiene-based (meth)acrylate oligomer, and a polyurethane-based (meth)acrylate oligomer; an acrylic-based monomer component; a plasticizer component; and a photopolymerization initiator component; wherein a total amount of the component (a) and the component (b) contained in the photocurable resin composition is 25 to 80% by mass, and an amount of the component (c) contained in the photocurable resin composition is 65 to 10% by mass, and wherein the component (c) contains a solid tackifier having a softening point of 60 to 150° C. and a liquid plasticizing component, and a mass ratio of the tackifier to the liquid plasticizing component is in a range of 60 to 30:30 to 10.
