Abstract
A curable resin composition for use in a sealing material for film liquid crystal panel, the composition containing: (A) a polyfunctional thiol compound; (B) a polyfunctional (meth)acrylic compound which has 3-6 (meth)acrylic groups and has a (meth)acrylic equivalent of 100-250; (C) a polyfunctional acrylic compound which has 2-4 (meth)acrylic groups; and (D) a photopolymerization initiator. The blending mass ratio of (B)/(C) is 0.1-1.0, and the ratio between thiol groups of(A) and polymerizable unsaturated bonds of (B) and (C) (thiol groups/polymerizable unsaturated bonds) is 0.5-3.0.
Claims2
A curable resin composition for use in a sealing material for a film liquid crystal panel, comprising:
- (A) a polyfunctional thiol compound having 2 to 6 thiol groups;
- (B) a polyfunctional (meth)acrylic compound having 3 to 6 (meth)acrylic groups and a (meth)acrylic equivalent of 100 to 250;
- (C) a polyfunctional allyl compound having 2 to 4 (meth)allyl groups;
- and
- (D) a photopolymerization initiator;
- wherein
- a blending mass ratio (B)/(C) between (B) and (C) is 0.1 to 1.0, and
- a ratio between a functional group concentration of thiol groups of (A) and a sum of a functional group concentration of a polymerizable unsaturated bond of (B) and a functional group concentration of a polymerizable unsaturated bond of (C) (thiol group/polymerizable unsaturated bond) is 0.5 to 3.0.
