  • Resin composition for sealing liquid crystal cells
    Patent number: 5908899
    Abstract: A resin composition for sealing liquid crystal cells which contains as essential components a rubber-modified unsaturated compound obtained by grafting a monomer having at least one polymerizable ethylenically unsaturated bond in a molecule with at least one rubber selected from acrylic rubber, silicone rubber, urethane rubber and conjugated diene rubber, and a coupling agent, a filler and a photopolymerization initiator. The rubber contained in the rubber modified unsaturated compound has a particle diameter of 0.2-5 .mu.m and a number average molecular weight of 1000-100,000, and the rubber content in the compound is 0.5-45% by weight based on the rubber modified unsaturated compound.
