摘要： The present invention provides 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 µm 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.

摘要： A resin composition for sealing liquid crystal cells comprising as principal ingredients epoxy resin containing a polysulfide modified epoxy resin, hydrazide compounds and fillers.
Said epoxy resin may contain a polysulfide modified epoxy resin expressed by the general formula (1) by 20 to 100% by weight in the entire epoxy resin and the average molecular weight of the entire epoxy resin is preferably between 300 and 3000.

where each of R¹ and R³ represents at least one organic group selected from a group consisting of bisphenol structures, aliphatic oxyether structures and aliphatic thioether structures and R² represents a polysulfide structure expressed by -(C₂H₄OCH₂OC₂H₄S m ) n -, wherein m represents the number of sulfur atoms contained in a polysulfide structure, which is 1 or 2, and n represents the average number of polysulfide structures contained in the above formula, which is between 1 and 50.
A film-made liquid crystal cell made by using the resin composition is excellent in adhesion, flexibility, electric properties and has high reliability.
